The Ledger

How big a task would it be to create a copy of https://github.com/ToonTalk/tt-wasm that provided a full first-person view 3D

Scoped a first-person 3D ToonTalk port; recommended a small draw-list prototype first.

Would option 2 be easier if we didn't try to capture the look of ToonTalk. There still would be trucks, vacuums, helicopters, robots, etc. but we would be free to come up with their design and aesthetics.

Estimated cost of an original-look port vs. a from-scratch aesthetic — roughly 1.5–2× for a much higher ceiling.

I've been reading about recent projects where LLMs use tools such as Blender to make 3D assets fairly quickly. E.g. https://www.linkedin.com/posts/emollick_sure-threejs-in-webpages-are-neat-but-codex-activity-7490226952260182017-tQe2?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAEKfQMBfjhvf4Dp4672Fuya8mJtzsaVb3A

Proposed Blender-scripted assets as a cheap way to test the look before committing to a pipeline.

Yes let's make a robot. If it is acceptable then we can explore getting it to pick up and drop items.

Built the first robot model in Blender, ready for pick-up/drop animation.

This looks good. Where are the files? How can I use the GUI?

Explained where the Blender files live and how to open/recolor the model in the GUI.

Very good start. Let's keep it this way for now and fine-tune later. let's see a web page where the robot picks up something and puts it somewhere else

Built the first web page: the robot picking an object up and setting it down.

Great. One idea to remember for much later is that the user could do some kinds of customization - e.g. change the color of things or choose among a few robot heads.
For now let's aim at nano-ToonTalk. The robot is already in its thought bubble and there is a infinite stack of numbers. The user can direct the robot to pick up a number, change its value (and operation later), and set it down on a pillar. Then when a number is placed on another number they combine. Later we can come up with something like Bammer (like an owl flying in with a hammer and combining them). There is a way to exit the thoughts which at some point could be a thought bubble over the robot that has the robot inside under user control. Then upon exit there is a way to get it to repeat what it was trained to do.

Scoped “nano-ToonTalk”: numbers off a stack, training by demonstration, a way to exit and replay.

Great. Let's introduce boxes that can hold numbers and boxes. Let's have a special pedestal that when the user put a number or box on it the robot enters its thought bubble and can be trained

Added boxes that hold numbers/boxes, and a pillar that starts training when something is dropped on it.

I saw something that wasn't right. With a box with 2 numbers if one number is picked up and dropped on the other It didn't end up on top of the other number but after a short delay they were combined. Or sometimes it shows up in the empty hole when the number in the hole was clicked. But again they are then combined correctly. And if there is empty hole we see the number dropped in the center but then end up in the right hole.
May as well fix this
[the console warning — 2 lines]
I expected, like ToonTalk, that after training I could modify the box on the blue pillar and that I could then run the training. But instead dropping a number on the empty hole put the app in thought bubble mode. I think placing a box on the blue pillar is the only way to enter thought bubble - not modifying something already there.

Fixed combine-on-drop and hole-placement animations; clarified how training mode is entered.

go ahead

(“go ahead”) — the robot now acts for real instead of resetting the world, and aborts with a clear message on mismatch.

can you create a github repository for this project or should I?
Working but the robot to move something from a box to another hole in the same box doesn't need to walk to the center and back
Let's introduce Dusty and a display of the what the robot needs to match in order to run (and keep running) that Dusty can modify.

Created the GitHub repo, trimmed a needless walk, added Dusty and a thought-bubble condition display.

📷
The thought bubble should be attached to the robot's head.
When clicking "Run what it learned" and there is a mismatch then highlight the part(s) in the thought bubble that isn't matching.
Let's add a duplicating machine instead of the Magic Wand. If you or the robot places something on it it creates a copy is nice animation

Attached the thought bubble to the robot’s head, added mismatch highlighting, and a duplicating machine.

Working well. Can we add a speed control that supports a very fast speed. And the fastest speed you don't see the robot doing anything - just what is on the blue pilar change. Also let's move the vacuum and duplicator to other side of the blue pilar.
And let's introduce operators (+, -, *, /, and ^) to the things you can type while holding a number. And we'll need fractions then.
Finally numbers with 5 or more digits don't fit well so we'll need shrinking digits.

Added a speed control with an Instant mode, typed operators (+−×÷^), and shrinking-digit numbers.

📷
You should see the operator and the block should change color
when the robot stops after performing its training due to a mismatch the mismatch should be highlight just as it when the run button is pushed for a second time.
Why did the doubling program stop in "instant" mode when it reached about 2 million?
Also in instant mode the objects should remain on the blue pilar

Fixed the operator badge/color, mismatch highlighting on replay, and a rule that a pass never ends mid-claw.

Let's have a way to save and load trained robots
When holding a box and a number is typed the box should change to have that many holes.
Why not make numbers like in ToonTalk? BigInts and when they are too big to display the digits get smaller so there can be lots of digits too small to see and then bigger on the right half of the number. This applies to numerators and denominators too.

Added save/load for trained robots, digit-typed box resizing, and BigInt numbers with shrinking digits.

Buttons shouldn't turn gray when you hover over them.
The duplicator should work when empty if you drop on the pillar top (the bottom of the duplicator).
When you take a number from the stack it should disappear from the stop of the stack and the stack should rise to restore its full state.
The description of the action says "what it was given" which is confusing - the blue pillar is better
I don't remember the ^ loop causing a problem in the original ToonTalk or the wasm port - can't we do the same here?
Shrinking digits is half right - it should start off full size shrink to "..." in the middle and then grow back to full size. Again copy the way ToonTalk does it.

Fixed hover-gray buttons, an always-on duplicator, and stack regrowth timing after an item is actually gone.

Give the app a favicon
The stack growing when an item has been removed should happen after the top item has been removed.
When a number is placed on another it should rest on top of the lower one briefly before being combined
The duplicator selection is fine (my mistake) but the animation could be improved to avoid two objects inhabiting the same space briefly.
Reset leaves something in the robot’s hand
The big change is that the robot shouldn’t do anything except when in its thought bubble (or when rerunning its training). The user is the one who moves things around otherwise. The blue pillar was a bad idea - training begins when something is given to an untrained robot. I am uncertain if the user should see her hand or if it should be “invisible”

Added a favicon and timing polish; the big change — the robot only acts inside its thought bubble, never for the user.

While holding a number or box I can't set it down on a pillar (what is the motivation now for pillars instead of a workbench?).

Explained pillars vs. a free workbench, and the tradeoffs of going fully box-relative like real ToonTalk.

Let's go full ToonTalk - actions relative to the box only

Rewrote robot actions to be entirely relative to the box it was given, ToonTalk-style.

Why can't the duplicator have 2 surfaces: an upper platform where something is placed (and scanned) and the current lower surface where the duplicate appears. Wouldn't robots be able to work then?

Split the copier into two surfaces — a scan platform and a delivery tray — so robots can use it too.

Robots in the original could place things anywhere in their cloud as a temporary work area. These are automatically vacuumed up upon leaving the thought bubble. All that persists in the original is the box the robot was given. But boxes are clumsy for simple arithmetic procedures so we could generalize that to whatever object it was given is placed back on the table (perhaps modified)

When during training the copier is armed the robot should be able to pick up things and move them to the copier

Gave robots a scratch work area and fixed a copier step-ordering bug that made runs abort early.

The robot doesn't do anything during training when I click on a number on the rightmost pillar
Also when the user clicks on the stack of numbers the number sometimes appears far from the stack while it should start somewhat above the stack

Fixed number-pickup drift and made vacuum-erase animate a rise from where the item actually lay.

Let's do that generalization - address things as (container, path)

Anticipating having multiple robots I think there should be a stack of miniature robots. When a user places one on the table and then drops an object on them they grow to full size and move behind the table and grasp the item.
Clicking on a trained robot miniaturizes it and the user can then drop it on the table. Dropping a trained robot on another creates a team.

Generalized addressing to (container, path); added a stack of miniature robots and team-forming by drop.

when I gave the robot a number it worked fine but then I thought to copy I should click on the duplicator and the robot would walk over there and place the number there and then in order to double would place the original and the copy on its special pillar
The way robot's do things should be as similar to how the user doesn't things as possible.

Unified the copier’s two surfaces so the robot’s actions are ordinary takes/puts, no special wand step.

📷
Regardless of where the user clicks on the duplicator (whether training or not) it should be placed on the upper platform
When training is over I think the robot should leave the object on its main pillar
The upper left message area should explain about using the vacuum when a robot doesn't match what it has on its pillar - and it should be briefly highlighted.
The robot in instant mode stops after N steps - this isn't clear to the user. Perhaps instant mode should somehow allow the user to specify the number of steps
Normally when I pick up a number I see a message describing the number - but it stopped doing that after a while. And now when I pick up a number it looks very big depending upon how I move my invisible hand - see attached

Fixed the copier’s drop targeting, restored the “holding” readout, and clarified Rounds is per-session.

Let's add tooltips to everything

Added tooltips across every clickable target in the workshop.

I don't think we need the "train again" button since you can always grab a fresh robot
The vacuum should be able to remove objects in addition to generalizing robot's thought bubble conditions.
Let's add a stack of scales - unlike the original they should accept 2 objects and don't need to be in a 3-hole box

Removed “train again”, let Dusty remove objects outright, and added a stack of two-pan scales.

I saw a good message about a box with 2 holes not matching a 1-hole box but then the red indicator went away
Erasing a box yielded a number with ? - we need something for erased boxes
Also we need a way to join boxes - dropping one on the side of another worked in ToonTalk - should work here too
Since we aren't using the space under the table let's move the vacuum there get a bit more space

Fixed box-erasure display, added left/right-sensitive box joining, and relocated Dusty under the bench.

📷
📷
The tip for scale should refer to holes.
We need a way to distinguish between -2 and subtract 2. I think typing '-' to make negative numbers should be the default, but now to indicate subtraction?
Let's add an undo button and control-z (or the like)

Fixed the scale tooltip, clarified negate-vs-subtract typing, and added Undo/Ctrl-Z.

When I used dusty on a box with 2 holes I was able to erase the numbers inside but not the box itself - it became a ?-number instead.
There should be a difference between dropping a box on the left or right side of another box in terms of how they join.
Let's add a stack of nests with eggs like in ToonTalk
For the time being don't worry about backwards compatibility with saved robots.
I think we can get rid of "Forget training" since there are now ways to get a fresh robot and vacuum away an unwanted one

Added nests with hatching eggs and real bird delivery; removed the now-redundant “Forget training” button.

The reset button says it clears away things but keeps the robots - that's confusing - maybe get rid of it too.
The robot puts things on the lower level of the copier and then can't pick things off the upper level but instead they drop down.
Pointing to a small trained robot should display its program
Save robot might have worked but load didn't seem to do anything
And optionally the user should be able to save to disk to share with others or move to another computer
I had troubles picking up a full nest - the cursor was as low as possible on the nest but I still grabbed the top item on the nest
I couldn't put a bird or nest into a box hole

Removed the confusing Reset button; fixed the copier’s upper surface and nest/box-hole handling for birds.

📷
📷
📷
the first screenshot shows that I couldn't give the box to the untrained robot - I tried several times at different locations
the second screenshot is just that the cursor (hand) was pointing to the nest while the robot was a good deal to left of that.
The third screenshot shows a loaded robot that used to expect a ?-number now accepts anything
I don't see any change in which platform the robot uses on the copier

Investigated give-to-untrained-robot and hole-vs-desk drops; fixed the copier arm reading as too low.

I think any size box should be joinable with another since these are like arrays
load worked

Confirmed any-size boxes can now join like arrays; confirmed Load works.

📷
a robot will sometimes put something down on a diagonal and when released it becomes parallel to the table instantly. Don't have any instant changes - a quick animation is better.
should say a box with 128 holes in screenshot and the advice about typing a digit doesn't apply to such big boxes
When a robot dropped a scale on a scale the dropped scale ended up on the table. I guess that's ok but if repeated all of the excess scales are at identical locations which is confusing - they should be slightly offset
load from storage worked but import file did nothing

Smoothed instant snap-to-flat drops; fixed a big-box tooltip, scale-stacking offset, and file import.

📷
the robot instead of going to the boxes to get one suddenly has one when running
A robot drops things at the center of a box and then it goes magically to the right hole - this is ok but would be better if it was dropped in the correct hole instead.
vacuuming a box in a thought bubble jumps to anything instead of any box (any number of holes). and it should be possible to vacuum up what is in hole to so it becomes an "any"
after naming a robot the export file still uses what was next to the "load" button, so I guess the idea is you need to click save before exporting - a bit confusing
Also let's add the robot's name to its chest display.
I think import should do what import followed by load does now
Numbers should display their value on the top face as well
The keep the front face as now but for the other faces let's display other forms of the same number. For integers that would include scientific notation and English
For fractions there are exact decimals (the digits shrink so only the first visible digits need to be computed), mixed fractions, scientific, English, and whatever

in the screenshot the tooltip says it adds but I am holding an exponentiation operation and I can't drop it on the number (if that is because it is too large the user should be notified urgently).
Finally for large numbers with ellipsis in the middle when looking up close more digits should be displayed. Same for long or repeating decimals.

Added multi-face numbers (scientific, English, decimal) and fixed a fetch-from-stack “sudden appearance” bug.

📷
📷
The hand is at right location and the tip says I can drop it on the robot's work pillar but clicks are ignored. I can drop it on the desk. If I picked up the robot, set it on the table and then gave the box to it everything was fine.
Let's have a way save and load everything (both in browser and file system)
If the decimal is repeating then if the repeating part fits place a bar over it, if it doesn't fit then end it with "..." - even for scientific notation.
When the robot gets something from a stack (e.g. a number) the stack should grow to replace the missing item AFTER the robot has removed the top item
I don't see the robot's name and the name isn't used in the tip when pointing to a robot.
When holding a box and a digit is typed that is less than the number of holes then the excess part should fall to the table when done by the player and to an extra pillar if a robot does it.
Typing when holding birds or boxes should add what is typed as label.

Fixed robot-work-pillar drop targeting; added save/load to disk, repeating-decimal bars, stack regrow timing.

Newer items placed on a nest by a bird should be underneath what is already there - the bird should move the stack of things on the nest to the table, place the new item, and put the stack back on top. The user or a robot cannot move the stack just the top items one by one. The nest and its stack can be moved by anyone.

Made deliveries land under the pile — the bird lifts it aside, tucks the new thing in, and stacks it back.

📷
📷
📷
📷
I want to have a way to obtain a copy of the object that was originally given to the robot to start its training. In ToonTalk the Magic Wand set to 'o' does this. Maybe if a trained robot is lifted up and dropped then a copy of its training object falls out. Or do you have a better idea?
The number in the screenshot should be 0.142857 with a horizontal bar over 142857 - and this applies to scientific notation too - so long as there is enough room - otherwise end with "..."
Regarding the robot's work spot let's have only one but when anything is placed on it a new grows up next to. This way there is no limit to the temporary storage for a robot but it isn't cluttered with 3 spots if not needed. Also they should look a bit different. Maybe the robot's stand should be a mini desk instead.
The Fibonacci robot used to work fine but now it stops after a few steps and seems to skip things
Instead of 1.00000 x 10^0 it should be 1.0 x 10^0

Added a way to copy a robot’s original training object; gave each robot a growable row of work spots.

While training a robot it couldn't grab the top of a stack on a nest - the user could when it was on the table.
If a label is typed to a nest with an egg then the label is given to both the nest and the bird.

Fixed pile-top pickup during training; a label on a nest with an egg now names the hatched bird too.

I don't see any way to grab a copy from a robot's thought bubble.
Use animation to show when the vacuum is active
when a robot works on a nest that is covered its thought bubble should have the top item only as if there was a nest. The robot will match either that number there or a nest with that number there (unless erased). If there is a nest there the robot will shrink and wait for a bird to deliver something. If a bird does and it matches the robot will expand and go to work right away.
If a bird is copied each copy will deliver to the same nest
If a nest is copied a bird when given something will copy itself with the object and deliver to each nest copy. Only the original returns to where it start from the others fly away never to be seen again after delivering their copy

Enabled copying from inside a thought bubble; animated the vacuum; defined nest/bird copy-and-broadcast rules.

An empty hole in a thought bubble should match anything in that hole

Made an empty condition hole match anything, and showed that permissiveness in the condition text.

Why is enabling github pages failing?

Diagnosed a one-off GitHub Pages deploy failure — nothing to fix, just a re-run.

If a robot is loaded while a robot is working or stopped then that robot should shrink and move to the desk and the loaded robot should appear behind the table. If a robot is paused on a nest it should stay behind the desk but move over and provide room for the loaded robot.

Made loading a robot correctly shrink and park whichever robot was previously at the bench.

Here is a list of major enhancements:

1. A stack of text pads similar to the original ToonTalk
2. A single notebook on the table that includes a blank notebook. Should include the ability to drop a text pad on them to open to the first matching page and a way to flip pages forward and back. Any changes to the notebook are persisted. Probably can remove the interface for saving robots once this is operational.
3. A way to grow the user’s table - perhaps a button that reveals corner handles
4. A way to save to disk whatever the user is holding (and for loading a choice of opening a file and dropping a file on the app)
5. A stack of recursive rooms (a bit like houses in original ToonTalk). They are just like rooms are now. A user can drop a robot into an empty room and the robot appears behind the work areas like now. A user also can drop an object on the room and it ends up where the robot works and the robot starts working. Birds can fly in and out. Some user action can swap the view so that the selected room becomes the room and the current room is miniaturized and placed on the user’s table in the newly expanded room. There should be an animation so this swap is easy to see. I’m open to suggestions for improving this design.

You can do them in the order you prefer.

Any questions?

Scoped five big features: text pads, the notebook, a growable table, save/load-to-disk, recursive rooms.

1. I think you need to study the original ToonTalk better - text pads were concatenated and dropping on the left or right edge determines the order. Here is the manual: https://toontalk.com/English/doc.htm - note that the full list of features depended upon Dusty being able to erase anything. I'm wondering if we should introduce an eraser tool (maybe named Ruby) and then Dusty is only for removing things. Either tool can be used on thought bubble contents.
2. Regarding notebooks again read the manual and ask any remaining questions
3. Maybe rooms should should have walls and a roof that can be toggled between transparent and opaque. When opaque they run in instant mode. When transparent they run at the speed control of the outer room. Each room conceptually has all the stacks and work areas and tools but the implementation need only add them when transparent. Swap idea sounds good.

order is good and yes drag-drop items appear in your hand and if something is already in the hand you see it placed on the table first

Read the ToonTalk manual per request; refined the text-pad/notebook/room designs against it.

Notebook statements confirmed. Notice the only way to remove a notebook (note there initially is only one but it contains a blank notebook) is to use Dusty on a notebook open to 2 blank pages.
Go ahead

Confirmed the notebook’s two-blank-pages removal rule; began building the notebook.

Go ahead with the notebook and Ruby

Built the notebook and Ruby the eraser, with a real distinction between erasing and removing.

Go ahead with the growable table

Built the growable table with draggable corner handles that persist across reloads.

Go ahead with the recursive rooms

Built recursive rooms with transparent/opaque walls and a view-swapping door.

📷
Ruby should work on objects on the table as well as in thought bubbles. When I used Ruby I saw Dusty animate
Text pads disappear when dropped on the table or into a box hole. They work ok with robots. I think the text should expand to fill the pad - not like in the screen shot.
I couldn’t undo accidentally turning a robot into a miniature.
The table resize handles don’t move - instead the camera does
I don’t see the notebook on the table
How hard would it be to add some textures to objects? E.g. text pads should look more paper-like and the table wood-like.

Fixed Ruby on tabletop objects, text-pad legibility, a mini-robot undo gap, and added object textures.

📷
The tooltip for rooms is for boxes
When loading a robot it becomes the active robot. But we need a way for a robot to pick up robots and place them in rooms (and more). I couldn’t put a room on the table.
You should be able to drop robots, birds, and empty nests onto notebooks. If the bird and nest are in a box they maintain their relationship. Otherwise when a bird is removed a new nest appears (with nice animation) and when a nest is removed it has a new egg in it and a new bird hatches.
I don’t think we need buttons for Dusty and Ruby to toggle whether they are asleep.

Fixed the rooms tooltip, dropping robots/birds/nests onto the notebook, and Dusty/Ruby toggling by self-click.

📷
There is empty space on the right and the stack of rooms is clipped. I'm wonder if a better layout would be to center the table (and it should be larger initially) while the stack form a semi-circle behind the desk and robot work area. The robot would need to often turn around to pick something from a stack.

Recentered the table with stacks arranged in a semicircle behind it, so the layout no longer clips.

📷
📷
Dropping a number on an erased text pad didn't restore the text pad and changes its contents to the digits of the number.
A robot in a notebook should be laying down and fit on the page with a small margin - not like the screenshot
There should be a way to minimize (and later restore) the panel in the second screenshot
Taking out a room should not make the new room be filled with what is in the current room. When it is transparent you should see a miniature copy of everything (the stacks, tools, robot work areas). Dropping a robot onto the room should install that robot and dropping an item will cause it to end up at the robot's work area and the robot will start working. Also when a trained robot is given an item it should start running after taking its position and the item is on its work area.

Fixed erased-pad restoration, laid robots flat in the notebook, and made a room auto-start on drop.

I'm unsure of whether when there is a mismatch that the object the robot was working on gets moved to the user's table. Why does it work that way?

Explained why a mismatch bounces the given object to the table, and proposed leaving it in place instead.

📷
Yes change what happens to the object the robot is working on.
A robot in the notebook should be shrunk down to fit on the page with a normal margin. Scales should also be laid down when in a notebook.
I couldn't combine 2 text pads by dropping one on the edge of another.
erased numbers and text pads other than in the thought bubble should not have ? over them
Dropping a text pad that can be parsed as a number on an erased number should become that number.
Clicking on a room in the stack just picks it up - no toggling of transparency until it is set down. Also the transparency doesn't toggle if something is held in the hand.
I was able to drop a robot in a mini-room but I couldn't drop a number in after that

Made a mismatch leave the object on the robot’s own desk; fixed notebook/room drop targeting.

📷
Much better but the robot should be lower on the page instead of sticking out.
When the room is transparent the tiny robot should follow the same speed that is set in the interface
What are our options for adding sound effects?

Lowered the robot on notebook pages; synced mini-house robot speed to the interface; scoped sound effects.

Go ahead with the procedural sounds and a volume control including mute.
Maybe other things have textures. The scales could be 2 types of metal, the nest twigs/straw/??, anything else?

Added procedural sound effects with volume/mute, and textures for scales, nests, the notebook, and rooms.

📷
Even robots placed on the desk should displays their thought bubbles
I put in the mini-room a robot that gives successively larger integers to the bird in the first hole. The second hole has the number that is incremented. Instead of seeing the bird fly to its nest the number became full size and changed as the robot ran inside. Also that floating number couldn't be grabbed or vacuumed.
When I'm holding a bird or nest the hand cursor significantly underneath the object. Scales and rooms too but boxes, numbers, and pads are fine
When I clicked undo after dropping a robot in a room the robot came out by a tiny copy remained. Same with any object.

Gave desk robots visible thought bubbles; fixed hand-height centering and undo losing a room’s inner world.

@"C:\Users\toont\Downloads\natural_numbers.robot.json"
The large number that changes and no bird delivery is still happening with the natural number generator in a small room - attaching the robot - perhaps the fact that the robot uses the copier causes this
Still can combine text pads other than dropping one near the center of the other.
In the 3rd screenshot when I move the pad closer to the near edge of the table the held item no longer moves but I can release it on that part of the table. Perhaps because I expanded the table?
scales tooltip drop refers to holes instead of pans
when I dropped a text pad in a box hole I no longer see it. the tooltip said it was empty but I was able to take it out of the hole

Fixed edge-drop text-pad joining and the carrying-plane clamp on an expanded table; fixed pad-in-hole display.

📷
📷
📷
It should be possible to get a copy of the original item used in training a robot from its thought bubble even when it is miniaturized.
I should be able to put mini-robots in box holes
In the first screenshot there is a 2-hole box in hole 1 but the tooltip says it is empty. Also while the 2-hole box can be removed from the hole it is not displayed as an embedded box.
This time testing natural numbers in a mini-house the bird flew out to the top nest&egg on the stack but wasn't seen again and lots of full size numbers began appearing on the desk (2nd screenshot). Not sure where the bird's nest went either. When I tried it with an opaque house the stack appeared on the nest&egg stack (see 3rd screenshot)
It shouldn't matter the order of dropping a robot and an object into a room - seems right now the robot must be first.
There should be a way to stop action in a house - other than entering the house and then clicking stop - not sure how

Fixed a room’s drop-order deadlock and gave rooms two separate ways to be stopped.

I don't understand why bird's have any trouble finding its nest (or nests). Each nest can have a guid and a bird flies to the nest (or nests) with that guid.

Switched bird-to-nest matching to stable GUIDs instead of fragile references, closing several delivery bugs.

📷
@"C:\Users\toont\Downloads\box.thing (1).json"
I was able to hold this box under the table (without trying to)
I was able to put a room in a box then I could take it out again. But then when I tried another time I couldn't even drop a room in a box hole
the stack of rooms should have some space between each one like text pads, robots, and nests do
When I loaded the attached I was able to remove the room for a hole

Fixed a box-hole path bug, evened room-stack spacing, and confirmed a loaded box’s room worked as designed.

You should be able to pick up a tower on top of a nest by grabbing it anywhere other than the top.
Since these towers can get large let's truncate the middle with a bit of text saying how many objects are being elided when ever there is more than 10 items.

Added truncated “N more” piles for tall nest towers, and let you grab a tower from anywhere but the top.

📷
The placement of the message is too high
Sorry I meant when you grab the tower you also pick up the nest at the bottom

Fixed the tower/nest grab to include the nest, message placement, and gave robots the same pile-grab rule.

save world didn't do anything. I see many copies of the following in the console:
[the console line — 1 line]
My hand was centered on the box in the robot's thought bubble but clicking picks up the robot (see screenshot 1)
Screenshot 2 everything was fine with the transparent mini-room providing numbers in order - but after about 15 numbers I made it opaque and the order of the numbers is wrong. And top 3 numbers are duplicated in half size.
combining text pads still requires a drop where the 2 pads overlap a good deal - screenshot 3 shows how it indicates a drop would be to the desk. And when the held pad was over the other pad no tooltips at all
Regarding the save interfaces let's simplify so there is only save held thing and save world which saves to disk. There then is only import file (it should be able to work for worlds as well as individual objects). Regarding robot names let's have the user type the name while holding the robot (still displayed on its chest). Let's allow typing while holding a house and the text appears on the sides (but not where the door is - by the way the door could be made to look more like a door)

Fixed the workbench-vs-pad drop message, and stabilized in-flight birds surviving a world swap.

📷
📷
when possibly about to drop an object into a mini-room the tooltip should briefly explain how rooms work not about toggling the roof
Switching to opaque still produces the incorrect order on the nest. When transparent it seems a fresh bird was being created each cycle since it flew away rather than back to where it came from.
After an opaque room has hit the limit of its round how I get it to resume running.
When typing names or text pads copy and paste keyboard shortcuts should work

In screenshot 2 I clicked on the stack of nests and the robot went a picked up a number instead - happened repeatedly

The thought bubble should contain a box with a robot and a room - both should have ?s since they automatically match any corresponding robot or room

Still can't grab the object in a thought bubble to obtain the original

Fixed a mini-room drop tooltip, in-flight bird disorder on opacity toggle, room-resume, and copy/paste.

📷
I pasted some emojis into a text pad - it worked but they are very faint. I think text including emojis should be fully opaque. Later we may introduce lots of settings so users can customize this.
Let's have the bird when flying have its wings extended
I couldn't inactive Ruby while the robot was running.
I erased a box and then undid it and the bird remained erased while the box and number were restored
robots in holes should be lying down and smaller

Made pasted emoji fully opaque, fixed an eraser-undo bug leaving a bird ghosted, laid robots flat in holes.

@"C:\Users\toont\Downloads\workshop.world (2).json"
I ran nat nums first transparent then opaque and it worked fine. But then I opened the door ran a cycle or two and then put everything back in the mini-room and the tab froze - even closing the tab did nothing until I closed it a second time.
In a fresh tab I loaded the attached world and the tab again became unresponsive - only the cursor was alive

Diagnosed and fixed a tab freeze from an infinite retry loop and redundant per-delivery GPU textures.

I don't see the bird's wings when flying. I see wings not really outstretched when the bird is resting.
When I set rounds to 1000 I noticed a couple second pause. 10,000 and it did 2300 or so and then paused and then the browser asked if I wanted to wait. Instant running should not interfere with the interface and should update now and then. After a long time it went up to 3600

Can we indicate somehow when a house is running - maybe it has a chimney that emits a little smoke or something else? Also why is it running so slow - a few minutes to increase the nest tower by about 1000 numbers

Cut a heavy room’s per-cycle cost roughly in half by lazily painting numbers’ secondary faces.

I ran 1000 cycles 4 times (3 in a mini-house) but now the interface froze for about a minute doing 1000 more
I didn't see anything coming from the chimney as it was running. I'm unclear how restart the house when transparent.
Regarding painting 4 faces the tower on the nest only displays 10 so can't that cost be mostly avoided?
Please generate a manual and provide a link to the manual from the app. Perhaps some of the parts of the manual can be interactive - e.g. when discussing birds have an illustration where things can be given to the bird. Maybe it should be an iframe so it shares all the implementation code

Chunked long Instant-mode runs across frames and wrote the manual, with live interactive demos in it.

📷
the first screenshot is from Chrome and the when pasted into a text pad (screenshot 2) it still seems faded.
screenshot 3 shows something is wrong it was generated by an opaque house on instant - first 100 (that worked fine) and 1000 more. There was a pause to chunking bottle runs sounds good. But why did they get out of order again?
Let's rename the app (and the filenames) to ToonTalk 3D
why does the robot have the tooltip in the 4th screenshot when I click on the robot on the desk a new robot comes forward from the stack
In general the try it frames in the manual should be minimal - only the items needed to illustrate the component
I didn't see a link from the app to the manual (or the manual to the app)

Fixed a stray click-tag bug, trimmed each manual demo to only what it teaches, and linked app ↔ manual.

📷
📷
📷
📷
the controls in screenshot 1 aren't needed in the manual unless the manual gives a simple robot example
Why no numbers example and dropping 2 didn't work right
Why not add an entry about the copier/duplicator - and let's give it a name - suggestions?
I still never see any smoke. I ran 5 times 1000 cycles.
I don't think clicking the roof is a good way to run the room. Maybe we should add a giant switch that toggles running or not - a bit like the attached image
dropping a number on the text pad is a bit tricky and the tooltips are no help. I think if the center of the number is left or right of the center of the pad that controls what letter changes

Trimmed unneeded manual controls, added a numbers example, and fixed number-on-pad drop targeting.

📷
It got stuck after 40 cycles despite the 100 rounds and notice 2 birds got stuck on the roof - the app then froze
I did a test where the nest was in a box hole and the bird didn't fly there. The nest in the box came from the notebook - when I put that nest on the desk it works.
When a nest with an egg is dropped in a hole the egg should hatch and the bird flies nearby and the empty nest is in the hole
Let's add something about navigating the 3D space to the manual
Nest color is too similar to the desk color

Fixed egg-hatching inside box holes and a room round-limit stall; added a manual navigation section.

I’m wondering if I should have asked you to read the ToonTalk manual earlier. Clearly some misunderstandings would have been avoided but I wonder if some innovations in the 3D version wouldn’t have happened due to the copying of the original ToonTalk design.
Another thing I’m wondering about is how some ToonTalk programs involve many houses. Some robots caused houses to be built and some of the robots in those houses built more houses. I’m worried what we have now won’t scale. I can give you an example if you need it.

Discussed reading the real ToonTalk manual and C++ source, and scaling concerns for many-house programs.

The example was a simple context free grammar used to generate a stream of random sentences (arriving on a nest). We would need to have a random number generator but otherwise we could program it in ToonTalk 3D. But several dozen houses were involved - now a more sequential version could be built but the concurrent one is more natural in ToonTalk. Or think of a doubly recursive Fibonacci program.
The divergence audit would be very good though we'll to update it as proceed.
Maybe it's time for you to read the C++ of the original ToonTalk to see how I addressed these recursion issues. I think it's all here: C:\Users\toont\dev\tt-wasm\source

Received a multi-house grammar example; began DIVERGENCE.md, the audit of gaps against real ToonTalk.

Your plans looks good, go ahead. % for modular division will confuse students - what are some alternatives?

Approved the divergence-fixing plan; discussed alternatives to “%” for the mod operator.

go ahead first the sentence generator and later the manual

Built the sentence generator; queued manual sections for dice, box-splitting, scales, robot-built rooms.

📷
I see the same sentence 4 times "the cat likes the frog." - dice have no tooltips and it is unclear how they are supposed to work - they are always showing 3
When the house is transparent and the speed isn't instant I'm not seeing the robot move around
When opened the door the Scribe robot worked fine. The bird flew to the original room that was showing it was working (smoke) but why should
Let's add the Fibonacci example and the Bank Account too
Text pads in box holes should be laid flat and legible as possible (not like the screenshot)

Fixed duplicate-sentence and dice-tooltip issues; built the recursive Fibonacci and bank-account examples.

📷
📷
📷
📷
In the manual there is no need for the robot's work areas (unless of course a robot is involved) and any stacks can be moved closer
The text pad entry should also have the number stack so the user can explore what it does
Dropping a text pad on a number could select the Nth letter (if the number is an integer in the right range) - and in any case the tooltip in the screenshot is wrong
I noticed that 1/6 doesn't have an English face (by the way at some point we should make the app customizable to other languages) I'm not sure whether "one sixth" or "one over six" or "one" "six" displayed vertically with a bar between them is best
Let's remember later to make the app behave better on mobile devices
Are we still "bottling away" things? If so, why? Or is that with the upcoming engine split
The smoke means "this room has mail to absorb." - let's only use smoke for houses that are active
If a house is running and the door is clicked then the robot should start working as soon as it is full size
The sentence generator is worth keeping but later we should do a simple grammar-based version
Regarding this example "runs on a box of the number 0 and anything or nothing and anything or nothing and anything or nothing and anything or nothing and anything or nothing and anything or nothing and anything or nothing · leads 19 more" - let's just say anything (no "or nothing") and what does "leads 19 more" mean? Should "more" be clickable?
Robots still don't fit well in box holes (screenshot 2)
Screenshot 3 shows the robot used its second extra work area while the 1st one was empty
When a robot takes a robot out of a hole it becomes full size rather than the usual mini size.
Screenshot 4 the tooltip correctly says the robot can be dropped in hole 2 but releasing it doesn't do so. Though I can drop it in the hole if I move the robot and then click

Trimmed manual demos further; added the numbers stack to the text-pad lesson; noted mobile support for later.

Let's remember for later to introduce long-distance birds (maybe WebRTC is best for this?)
Another thing for later is discuss is whether when multiple houses are running we could make it run multi-threaded
Later we should discuss importing media and associated sensors (and interface sensors)

Recorded long-distance birds, multi-threaded houses, and sensor/media import as future work — no code this turn.

📷
📷
📷
Turning a robot red that can't proceed is fine but all the other robots shouldn't change
When I picked a text pad off the nest stack all was well except the pad was behind the tower so unseen until moving it out from behind
when I loaded the bank account one of the boxes has double contents per hold
All of the example programs should have text pads on the table with brief explanations and instructions

Fixed a stray-robot color bug, a pad hidden behind its pile, and added instruction pads to every example.

📷
@"C:\Users\toont\Documents\ToonTalk\divisiontester\My Programs\divisiontester.tt"
when holding a text pad with more text than can fit in the message starting "holding" we need a way to easily see the entire text - do you have any ideas? Or should instead there be a way to get the camera to move so it is easy to read the text pad?
When I tested the bank account the robot "magically" copied a number without taking it to Mimi. Also I its use of Dusty should be shown
Let's extend the bank account to respond to withdrawls that are larger than the current balance. And the Teller should be in a house so illustrate its encapsulation
If a robot isn't working or waiting on a bird then if the user gives an object to another robot the stopped robot is miniaturized and placed on the table and then the robot given the object begins to work full size
Why isn't fib like this:
To fib n
If n < 2 return 1 otherwise return fib(n-1)+fib(n-2)
end
Regarding the sentence generator - add a more advanced version that follows context-free grammar rules like the attached ToonTalk program
When the user is holding something over another object that object should wiggle - even if it is inside a box or something else

Read a real ToonTalk division-tester program; scoped the bank-account rework and a data-driven grammar.

what is the status of removing bottling

Explained the status of removing world-bottling: still a plan, a real architectural rewrite, not yet started.

📷
📷
Let's removing the bottling after fixing the following minor issues:
duplicating a robot produced a full size robot instead of staying mini
When I ran fib it ran for a while and the stopped - see screenshot (let's retest this after bottling is gone)
screenshot 2 is such that sometimes when I click it ends up on the desk and sometimes in the hole
Let's have the current hole wiggle even if empty instead of the entire box

Removed world-bottling — worlds now live and step through one shared interpreter instead of being serialized.

Go ahead. Also I'm curious if the code shrank or grew when you made this change?

Rewired bird delivery through one wake-up path; re-verified every example after the bottling removal.

📷
Now the robot is too tiny when working behind its work surface and the user's desk
When a robot uses Dusty it seems to happen instantly - I don't see Dusty move - maybe it is too fast - how long should it take?
Why does the fib result in the screenshots have tabs or wings coming out?
Switches on houses don't have tooltips
I can't grab a copy of the original from a robot's thought bubble - also the thought bubble contents should also wiggle when selected
Dropping a number on a die shouldn't do anything - it makes the die look very strange - see screenshot 3
I'm beginning to think that contents on the table should go into a mini-house when another house is entered - these are items the user has not any robot

Fixed tiny-robot scale at rooms, animated Dusty properly, and labelled the mini-house holding the user’s table.

📷
📷
📷
The nest label should not collide with its stack - maybe it should be displayed below the nest.
second screenshot shows immediately after loading the bank account example - there is the orphaned thought bubble. Entering the house puts teller there with his thought bubble - still can't get the original training object - I understand it wasn't trained but you should be able to make it load with an available original
when I click "run what it learned" the robot becomes full size but does nothing - screenshot 3 shows its box floating without a work area and it is medium size rather than full size - it was full size when I entered the house but it became medium size when I put it on the table and then gave it back its box. I guess it is waiting for something but that isn't clear
when I run the bank account without entering the door it works fine but the bird doesn't fly out and move the stack around - it just appears in the stack (speed was 1)
I think things should stay on the big desk and not end up in the desk in a house (they don't need desks - just robot work areas)

Diagnosed the orphaned notebook thought-bubble and a rooms-overcharged-for-rounds performance issue.

houses shouldn't have the small desk at all
Are we still using bottles? "0.5–1.2 s per bottle for a single bank transaction"
go ahead and do the performance pass

Removed the small desk from inside houses; ran a performance pass that sped Fibonacci roughly 60%.

📷
I loaded bank account, opened the door and here is what I saw. There is a desk in the small house. The items before entering the desk are no long accessible. And the robot's box is now on the table rather on the the robot's workspace

Fixed opaque rooms drawing no furniture, and labelled the outer world “your table” so nothing feels lost.

It isn't any better. What I want to do is use the 3 boxes, the bird, and the nest while watching the robot run in full size. So I should be able to enter the house and still have those objects on my desk. So I can give those messages to the bird and watch the robot. And what purpose does the desk play inside mini rooms? The desk is a global object in my thinking. Does this make sense?

Redesigned rooms so the user’s own desk stays reachable while a robot works full-size inside.

@"C:\Users\toont\Documents\ToonTalk\divisiontester\My Programs\divisiontester.tt"
bank working now. the robot and its work areas don't need to be as tiny as they are in the screenshot
Let's not have smoke when transparent since it gets in the way and isn't necessary
The chimney is still visible when transparent
Wiggling when selected is no longer happening

Your bank is OK and we should keep it as an example but we should also have an example that works like the attached tt file

Kept both bank examples; ported Ken’s original division-tester idiom; made a filled input auto-start the robot.

I don't understand "our robots can't do that, because typing is recorded as an absolute value and the amount is a wildcard — so this robot drops a "times −1" on it instead, which works whatever the amount turns out to be." - I thought your fib robot picks up a 1 and drops a -1 on it.
I'm confused about how your bank robot uses a scale - is there a team of robots but they aren't animated as such? How does the scale orientation matter if not when matching a thought bubble?

Clarified the “times −1” subtraction idiom; re-verified all example worlds and updated the docs.

@"C:\Users\toont\Documents\ToonTalk\divisiontester\My Programs\factorial.tt" @"C:\Users\toont\Documents\ToonTalk\divisiontester\My Programs\swap.tt" @"C:\Users\toont\Documents\ToonTalk\divisiontester\My Programs\append.tt" @"C:\Users\toont\Documents\ToonTalk\divisiontester\My Programs\reverse.tt" @"C:\Users\toont\Documents\ToonTalk\divisiontester\My Programs\n-to-1.tt"
Here are more original examples to add to the examples folder

Ported five of Ken’s original ToonTalk programs (factorial, swap, append, reverse, n-to-1) into examples/.

📷
Moving from holes to pans is the right move.
The new bank account didn't include the bird and its nest wasn't in the first hole and the bird was missing. When I got a new nest and sent the first message and in the area where the screenshot is explained what was wrong but too soon it was replaced by the inappropriate message in the screenshot
A team when on the user's desk should display them all. The user should be able to pull the team apart, add new members, and reassemble as desired.
The append robot worked fine but after it finished the upper right advice was that the user might might want to remove so things from its thought bubble. Perhaps the final append robot should remove its box to signal termination. Or maybe we need to design an alternative to exploding houses. Maybe vacuuming its box is good both for in the room and in mini-houses. A mini house without an object for the robot to work on is dead so perhaps should shrink away to nothing.

Investigated a missing-bird report (couldn’t reproduce); re-verified all eleven examples pass.

📷
The animation of the box when it is dropped on a robot on the desk currently is that the robot moves in place and then the box does (very quickly) - I think it should drift over to the robot's work platform as soon as it is dropped on the robot.
zero-hole boxes should fit into holes better (see screenshot)
n-to-1 is working fine but at 1x speed when it removes the old bird it looks magical - no Dusty appears
When I clicked stop the robot (and bird) stopped just fine. But then when I clicked run it could continue since the state was left half finished. Maybe stop should finish the program (maybe instantly) so it can be resumed
sometimes team members work fine but are miniaturized as they are working as part of a team

Fixed a robot’s drop-onto-desk animation, and named two measurement mistakes that had cost real debugging time.

📷
📷
📷
account looks like the first screenshot now - it isn't working as I expect
I put the spare nest in the first hole and gave the 3-hole box to the team (I think teams should line up one behind each other rather than side by side). When I give a deposit message to the spare bird I expected it to cover the nest so a robot runs. A robot does but what it does didn't make sense. It left the message in the first hole and responded with a copy of the deposit message to nest that I don't see what its purpose is. The nest in the first hole should be for processing incoming messages one by one and updating the state and responding to queries.
second screenshot has a nest in the first hole but it isn't displayed (though is label is)
stopping and then resuming isn't working, e.g. n-to-1 when stopped and then run ends up repeating a
number. And "junk" ends up on the desk that shouldn't
screenshot 3 shows that zero-hole boxes in a hole still don't fit in the hole
Robots in teams should line up with the leader in front - and only the leader should receive objects

Diagnosed a Rounds-limit-vs-message-count conflation, and a rapid double-Stop-click race.

📷
📷
With the cursor on the box the contents are wiggling which indicates that a click would pick them up but instead a click correctly picks up the box
why do we need the spare in the account example? When I gave the query message I see two replies (second screenshot)
On the desk I see a bird clear its nest and put the item on the bottom and put the rest back on - this is good - but I don't see that when a robot give the bird something - it is inserted at the right place by the bird but I think it shouldn't be different from what happens when a user does it
When a team is given something the leader animates to its work area but the rest move later - why don't they all move together?
How should we deal with the robot putting down an item - e.g. a box with many holes - on one of its spare work areas? Now they don't fit and overlap with items on other platforms. Either the platform should grow to accommodate (but that has limits) or the item on the platform needs to shrink to fit
grammar world produces the same sentence (6 times)

Fixed box-vs-hole click precedence; couldn’t reproduce a repeated-sentence report; explained the spare nest.

grammar world working now
What is on our todo list? Have you been updating the manual?
I'm also thinking of adding an AI-powered Marty the Martian. We can build a user provided API keys version and a Claude artifact that is keyless

Confirmed the grammar-world fix; reviewed the roadmap; scoped a keyless-artifact Marty the Martian.

I agree Marty shouldn't create programs but in addition to answering question he can demo the use of the different kinds of objects and tools.
Can you create an artifact or do I need to upload something you create to claude.ai to do so? And I've not heard of the artifact's asset story - how does it work?
Regarding "should a robot in a thought bubble match only a robot with the same name (the original) or any robot (ours)?" I think erased robots match any robot. Otherwise only if the robots have the same name (if any) and the same program.
I'm wondering if we should do 1, 2, 3 (but we don't need to stick with single character names for operators so maybe "mod" instead of % and "set" instead of =), 4 and 6 - sensor should be postponed. Once this is working we'll return to Marty.

Locked Marty to demoing rather than authoring; set the robot-matching rule; scoped five divergence fixes.

📷
scales with text are working but display poorly - see screenshot
text pads and zero-hole boxes look too much alike - let's give boxes a texture unlike anything else
And while we are at it let's make eggs robin egg blue

I don't understand "I deliberately did not do the team→box half: dropping a robot into a hole is exactly how fibonacci-recursive and reverse carry a spare team, and that gesture has to keep meaning that." dropping a robot team on a 0-hole box is different from dropping into a hole

Remember for later that we may want to re-implement ToonTalk's puzzle game

Fixed scale-with-text display, gave boxes a distinct texture, made eggs robin’s-egg blue (an sRGB bug).

📷
Let's do Marty now (and also fix dropping a team of robots on a zero-hole box - nothing happens now and tooltip is wrong)

Built the first working version of Marty the Martian; fixed team-onto-zero-hole-box.

Marty gives too much information all at once. Maybe there should be a "next" button or the like. E.g.
[Marty answering, pasted — 7 lines]
And it would be nice if Marty moved near to what he was demonstrating (but careful not to obscure it).
And he had a mouth

So if Marty responds and I have yet to provide a key so is that just canned responses? Make this clear in the "how does marty think"
Let's provide options for choosing between Claude, Gemini, and ChatGPT (and which model)

After providing the Claude API it answered my question well and then went on doing distracting other things (computing 42):
[Marty answering, pasted — 7 lines]

Added a stepwise Next/Stop demo runner, a mouth, and a Claude/ChatGPT/Gemini provider picker for Marty.

Let's add voice input and output options (speech input I think isn't currently permitted in artifacts)
This wasn't good:
[Marty answering, pasted — 9 lines]

I started over again with Claude and it wasn't much better:
[Marty answering, pasted — 6 lines]

Also for the demo the numbers were held by the user not by Marty

Added voice input/output for Marty; started having him hold demo props instead of the user.

📷
Worked much better except Marty did everything from behind Mimi - he moved there and the numbers moved on their own. But then I asked:
how can I see it as a decimal
In this workshop, numbers like 1/5 stay exact — ToonTalk doesn't turn them into decimals, since that could lose their exactness. So you'll always see it as a clean fraction, not a rounded decimal!

I wonder if Marty needs to be provided with a textual version of the manual to base its answers on

Moved Marty’s presenting spot so he’s visible and near his demo, instead of hidden behind Mimi.

Marty's voice doesn't sound very alien.
Mary hold numbers but then they quickly move on their own to the desk. And I don't see him go to the stack to get the number.
the following was working well until the last question
[Marty answering, pasted — 9 lines]

it just stopped and had that formatting problem - or was the maximum response too low?

I asked the following and got a good answer but then when Marty demoed it did the 25+17 instead
[Marty answering, pasted — 2 lines]

Gave Marty a properly alien, less-repetitive voice with a picker; his honest sorting answer was confirmed correct.

Yes, Marty did well on sorting but didn't seem to know that n-to-1 referred to the counting down example. When in a fresh test when I mentioned counting down it gave a good answer.
I think the pauses in speaking is too annoying - make it much more subtle
When I tried any of the non-English voices they sounded very high pitched and fast. Last I experimented with this they just sounded like someone with an accent. The English voices worked fine
Marty's movements are better but he moves under the table with his antennae sticking through. He moves to the stack and picks fine but then there is some tossing rather than moving and releasing an object

Taught Marty each example’s file name, softened speech pauses, matched voice to browser language, moved him off the table.

Please create a web page describing the making of this app. Include how early efforts did not involve the ToonTalk manual and how things changed after you read it.
I think Marty should float in the air to pick things up and place them.
Marty still wants to show the addition demo despite the context. See the following:
[Marty answering, pasted — 13 lines]

Wrote the making-of page; had Marty float to pick things up; added a powers demo so he stops mis-demoing addition.

Marty goes to the stack fine and gets an item but instead of turning around and taking the object to the desk the item flies to where it should go

Fixed Marty’s carried objects flying to position instead of moving with him, by pinning the shared hand.

It showed 25+17 and it went to the stack, turned it to 25, came to the desk put 25 down, went to the stack, turned it to 17, and then stayed there and the number magically flew on top of the 25
After fixing that make the artifact version for testing

Verified the last “magic flight” fix, then built the packed single-file artifact version for testing.

working fine except when Marty runs underneath the desk his antennae poke through
Regarding the artifact version I believe about 1MB is the maximum. I don't understand what you wrote earlier about inlining "The catch is the CSP: an artifact can't fetch anything from another host, so the artifact build needs three.js and GLTFLoader inlined."

Fixed Marty’s antennae poking through the desk; clarified the artifact’s real size limits and inlining.

Marty's demo of using Mimi didn't involve putting things on the copier - they just appeared there

Routed the Mimi/Dusty/room/notebook demo steps through the same walk-to-target helper so nothing “just appears”.

The voice reads "Brain: ChatGPT (OpenAI)." so turn these kinds of messages into a sentence

Changed “Brain: ChatGPT (OpenAI).” into a spoken sentence, “Switched to ChatGPT as my brain.”

When I tried to train a robot to take something from a copy of the notebook I see "The robot expected something in the right page of the notebook and found nothing." when something is very visible (a die). Then when I ran the robot it grabbed the item it couldn't pick up during training but it grabbed it from the original notebook on the desk (if it was open to that page). I think a copy of the desk notebook should not have any links to the original.
Also since the notebook is persistent I think it should be linked to a user name. So a user name should be provided an start (remembering the previous name). The notebook is linked to the name.

Fixed notebook-copy training to address the exact notebook given; added per-user notebooks with sign-in.

📷
I couldn't undo removing something from my notebook
I don't think Dusty should be able to vacuum up the user's notebook - he should refuse with a message
The message area (the screenshot) should have a way to toggle whether it is spoken (and which voice to use)
I guess the user's notebook should wiggle when selected since that makes it hard to click the arrows to flip pages
I switched user from "Ken" to "Ken 2" but I didn't get an initial notebook I got what looks like my usual notebook

Fixed notebook undo, made Dusty refuse the user’s own notebook, added a speak toggle, wiggle-not-lift, sign-in bug.

My computer rebooted and I don't see where to restart the 8311 server

Restarted the local dev server after a reboot.

📷
Here is what the app looks like when I load it. Marty is barely visible and Dusty and Mimi are offscreen. Being close to the desk is good so maybe the 3 of them should be on the sides of the desk instead. Maybe Marty on the left since Dusty and Ruby are a bit like Mimi
After doing this please update the making of doc (and give it a favicon)
Also the making of and the manual should have links to a post I am writing: https://docs.google.com/document/d/1gwSygWYhvqXttB8eqZZdZbAmCEYeMUI2RLeaKsx9sVE/edit?usp=sharing

Moved Marty/Mimi/Dusty/Ruby beside the desk; fixed a walk-order race; updated the making-of page, favicon, links.

Can you make a web page that lists every prompt I submitted here and a very brief summary of your response please

Published a first version of this ledger — scoped, mistakenly, to only the current session.

I meant the entire conversation starting 6 days ago

Rebuilt the ledger to cover the entire six-day conversation — this page.

can you find the exchange we had about the consequences of building for 3 days without reference to the manual or code of the original and reproduce it

Found and reproduced the 18 August exchange in full — the manual-as-arbiter answer, and the C++ reading that followed.

At one point Ruby could erase a number in a thought bubble and then a second attempt to erase used to turn it into any object but it doesn't seem to work now

Ruby's second erase click was being swallowed while she was still flying home from the first; the click now lands.

now when I trained a robot by giving him a number the robot becomes very small but is trainable.
I trained a robot that duplicates what it is working on drops it on the original. It doubles numbers fine and doubles the number of holes in a box fine. But when placed in a transparent house the box grew very fast (I thought transparent houses were suppose to follow the speed setting). The box punched through both walls and soon disappeared.

Rooms now scale their contents to fit, so a doubling box stops bursting the walls and dragging the house away.

📷
Here is a screenshot where I found the missing house on the floor and the box is very long. The box should have been scaled to fit in the house

Confirmed the house had not vanished — the box had grown wider than the room and carried it off.

The robot doubling a box in a quickly made the interface very sluggish - changing the camera was updated every 1 or 2 seconds. When I saved the world it was 11MB. In a fresh instance I loaded the file and clicked on the door - the animation of it expanding took many seconds. The box has over 500,000 holes. The speed was 1 the whole time.
I think users might do things like this but we need to be sure the interface doesn't become so sluggish - I wonder if all the holes are being computed even those far off screen or unseen

A long box now draws only its first and last six holes: 500,000 holes went from a million scene objects to twenty.

📷
has 10/7 twice when the one on the side should be "1 3/7" (or maybe "1+3/7" - I'm unsure)

Wired up the mixed fraction, which had been written and connected to no face — the top now shows 1 3/7.

Updating the file format is fine. But for the future can we include version numbers in the files so changes won't break things

Stamped a format version on every saved file; a file from a newer build is now refused rather than half-read.

📷
also can you improve the line breaks in the attached

Stopped the word-wrap accepting a font size that had to split a word — “ten sevent/hs” became “ten / sevenths”.

please update the Making Of doc

Added the “Half a million holes” chapter, with what each layer measured before and after.

The ledger and making of had 117 entries several hours ago - we've done several more since. please update this

Rebuilt both: found the extractor had been missing every message sent mid-turn, and recounted.

Other than sensors in ToonTalk the language has no possibility of concurrent side effects to the same entity. Many sensors both read (e.g. x position of a picture) and write (an update changes the picture’s position). At least sensor updates can be atomic.
A cleaner alternative is that a bird is associated with a picture’s x position and it can take messages to query or update the value. This is like actors and concurrent constraint programming which inspired ToonTalk’s computation model. It is also like how APIs work.
Sensors are much easier to use and understand. But they aren’t user definable. A user can build a message interface to a capability that bottoms out in sensors. For example, a Logo turtle can be defined to accept forward and turn messages but can’t be given a sensor interface. The sensor interface pushes towards Cartesian geometry over turtle geometry.
Do you have any ideas on how to have the best of both?

Sensors are the one place ToonTalk allows concurrent side effects to the same thing, and they are not user-definable. Argued the case out rather than coding it.

Now I’m wondering if ordinary birds are all we need.
Consider an imported image. Some user action (perhaps “flipping it over like in ToonTalk”) obtains a bird that can be given boxes such as [‘update’, ‘x’, 100], [‘query’, ‘y’, bird], [‘rotate’, 30], …
Also there is a way to obtain a bird to a number. The bird responds to boxes like [‘update’, 42] and [‘query’, bird]. Numbers also have a nest associated with them that receive messages like [‘dropped on top’, bird-to-dropped-number]
Then relying upon a bird for a picture, robots could be trained to use the number bird to send messages to the picture bird to, for example, be an x coordinate gauge. It would only update when needed. Another robot could be waiting on the number’s nest to trigger a message to the picture to change it, e.g. its x coordinate.
As you point out, bubble matching would need to be extended so that if any mismatch (including scales) is due to a number with associated robots will then suspend until the number’s nest receives a message in which case the match is tried.
Is this clear? How does it compare to your glass nests?

The resolution: ordinary birds are all we need. Sensors stop being primitives and become an idiom — a back you can flip to, a bird addressed to it, messages as boxes.

I agree with “This is, of course, ask-suspension from concurrent constraint programming: the bubble is an ask, live numbers are store variables, messages are tells.” except I’m sure what you mean by store variables.
The robots implementing a gauge can be anywhere but typically will be on the back of numbers, perhaps placed in houses but houses make it more awkward to see what robots and boxes are involved. But if users can place (and size) things on the back as desired they should be able to layout and label things to remedy this.
Copies of live numbers should be live and behave identically (unless their backside is modified).
I like the idea of operation-numbers as messages. We currently support [mod, 30] so a user’s [rotate, 30] isn’t very different. It is nice but limited to one-argument messages.
Stopping echo loops is good.
Yes let’s start with pictures and then sounds (and I guess videos too but later). Messages to boxes and robots is a cool idea to consider later. I just thought about dice. Perhaps they should be unmodified but they are currently a message to the number underneath that is something like [add, random(1, 6)] which backsides they could do more. Not sure about this and let’s come back to it later.
We still need to think about mouse and keyboard sensors. I guess there is just a notebook with nests that receive events from these things.
Another thing we need to consider is how to deal with inexact numbers. At some point we should introduce trigonometric functions and non-integer powers. I think they should conceptually (and perhaps implementationally) be rational numbers with a flag saying they are inexact. Though floating point would be much faster. This may affect identity but maybe only in preventing echos?
Rather than update divergence doc, let’s start a new doc once we settle on an initial plan/spec.

Named the lineage honestly: ask-suspension from concurrent constraint programming, with the one real disanalogy — that store is monotonic and ours is stateful.

All looks good - write the doc. I think inexact numbers should look slightly different
You write "A back is a house with no walls..." - there may be multiple wall-less houses on the back

Wrote BACKS.md. Inexact numbers must look different on the block; a back is a tabletop that can hold several wall-less houses, not one house without walls.

Include an estimate for how much work this will be

Costed it: roughly six to nine working days, in the order semantics, then payoff.

I believe we didn't add a license to the repository. I happy with a permissive license so is MIT the best choice? If so can you add it please

MIT, and why not Apache-2.0 — no patent exposure to speak of here. LICENSE added.

mention in README sounds good - no need for a badge
And the readme should have a link to my post about this project: https://docs.google.com/document/d/1gwSygWYhvqXttB8eqZZdZbAmCEYeMUI2RLeaKsx9sVE/edit?usp=sharing

README gained a link to Ken's write-up and a License section. No badge.

Regarding the running it section suggest that those who want to run it unmodified use https://toontalk.github.io/toontalk-3d/toontalk-3d.html
And I refreshed https://github.com/ToonTalk/toontalk-3d?tab=readme-ov-file but I don't see the pointer to the license - I think you didn't commit the changes

Running It now points at the GitHub Pages copy for anyone who just wants to use it — and the earlier commit had never been made, which is why the link was missing.

For those running on a version of Chrome that has Gemini Nano built in (I think all desktop versions) add the option of using it keyless for Marty.
I think the default voice for Marty should be female when feasible.
Also I think currently if a user changes Marty's voice is applies to all users - it should be specific to the user that changed the default

Gemini Nano as a keyless brain in Chrome, a woman's voice by default, and voice settings moved under the signed-in name so one person's choice stops being everyone's.

All looks good. I'm unsure about .claude/launch.json - what is the harm in committing it?
Provide feedback as Marty is thinking (especially since Gemini Nano is slow to load first time) Perhaps using the Marty 3d model to show he is "thinking" and users should wait.
Also when Marty is demoing he first moved to the corner of the table where he will later drop things and then moves off to the stack of numbers and continues fine. Is there any need for him to visit where he'll be dropping later?

Marty shows he is thinking — dots over his antenna, a hot antenna light — and stopped walking to an empty corner of the table before every demonstration.

I tried the app on my tablet. All worked but you can't see what you are holding. I realize it can't follow like how it follows the mouse. Furthermore it wasn't clear how to type anything while holding something. Maybe you have a better idea but maybe the held item should appear somewhere with a button for using the keyboard.
Also the canned speech refers to the Claude artifact that we gave up on.

The tablet report. A finger cannot lead the hand, so the held thing parks where it can be seen; a hidden field gives the keyboard something to appear over.

Also the menu bar at the bottom should have a full screen toggle button

A full-screen toggle, which on a tablet is what wins back the height the browser takes.

📷
when there is room like in the screenshot the full screen button should be next to the undo button
I don't see a tooltip for the speed
Thinking a user may not know the difference between the robot's stand and work spot I trained a robot to duplicate a number and then combined the copy and the original on the stand. First time I test it I saw "Ran 1× — then swept its own box away: finished, for good." and the number disappeared. I think in training the stand and work spot should behave identically.
Again I gave a fresh robot a fresh number and this time the robot was tiny as in the screenshot. But then I couldn't reproduce it.
I trained a robot to pick up a text pad to write "Ken ". So it turns every text pad into "Ken " but I expected it to add "Ken " each round it ran
On my tablet I was able to type to change a number but when I typed "hello" to a text pad I got "hhehelhellhello"
On the tablet I was able to type operators to a number except that it ignored the character for multiplication - I suppose it should work with other math operator symbols too

Seven at once. The two that mattered: a robot that carried its work off the stand was told it had finished, and its answer deleted; and writing on a pad recorded the result rather than the writing.

I took the result from the robot's stand and placed it on the desk. Undo then moved it to the corner of the desk, a second undo put it back on the stand.
Have you been updating the making of and the ledger?

Undo was right and unreadable — it hands the thing back to you, but the pointer is on the Undo button, so it appeared at the desk's edge. It waits where you can see it now.

also update
[the ledger's day list, pasted back for updating — 7 lines]

Brought the making-of and this ledger up to date, and gave the ledger a home in the repository instead of a temporary folder.

Can you make the ledger have my entire prompts except when they include copy and paste from generated text or the console or the like

The ledger stopped quoting the first sentence of each prompt and started carrying every one whole — only pasted material is cut, and each cut says what it was and how long.

Making of starts with "Six days, 119 commits and one 9,700-line file " which is out-of-date. Just after it says 10,414 lines

Recounted the making-of's opening line, which had been claiming six days and 119 commits two days after that stopped being true.

Can you make an index.html that is an alias for toontalk-3d.html

An index.html that hands anybody arriving at the site's root the workshop itself.

Is there a way to receive bug reports from users of 3D ToonTalk? And to find out how often it is run?

A Report a bug button that opens a GitHub issue with the browser and the build already filled in — and, for how often it runs, GitHub's own Traffic tab rather than anything the app phones home about.

sure

Wired both: the button, and a note on where the visit counts live.

I see a surprising number of clones - would these be AI agents doing it?

The clone count is almost certainly machines — CI, mirrors and crawlers clone; people who read the page do not.

Can you create a folder in examples that implements the examples from https://toontalk.github.io/tt-wasm/tt-wasm/build/infinity/index.html - Resort Infinity relies upon houses in a way that might be difficult to implement but the rest should work

examples/infinity: the seven Exploring Infinity activities, each robot in a room of its own so they all run at once. Resort Infinity is left out.

📷
for activity 1 I ran it a bit stopped ran it a bit more and stopped and the stacks are out of order in the screenshot. Also the house is switched off and can't be switched on so the numbers weren't appearing on the stacks until I clicked stop and then many quickly appeared

Two bugs from activity 1, both real. Couriers were arriving out of order because a slice could put forty of them in the air at once, and a room whose door you had opened was drawn as if switched off.

why "Rooms only work at a quiet moment" - that wasn't true of houses in the original ToonTalk

He was right and the note was wrong: houses in the original ran while you worked. The rule that made rooms wait for a quiet moment came out, and DIVERGENCE.md gained the step.

activity 1 is working fine even when I enter the door of the first house. I'll test the others soon.
As you can see in https://docs.google.com/document/d/1Dta9hKRzaGDGY1zTjz-_wPygdR3HacoYZlzMH-JMN2E/edit?tab=t.0 a month ago we dealt with the size limits and inability of Claude artifacts to fetch resources by asking the user to drop a zip file on the app at the start (it is then cached). Would that work for the 3D ToonTalk? If so can you also put this in your memory for future projects.

The Comic Chat trick — ask the reader to drop the assets in once and keep them — fits here too, and is now written down in memory for the next project.

📷

The probe that overturned a settled belief: twenty thousand frames at a steady sixty a second, published as an artifact. The loop was never what broke.

📷
📷
the artifact works fine
A minor problem I noticed is that because the provider width has increased with the addition of Gemini Nano the model name gets truncated
When the robot's actions are few it is ok that the save/load buttons are at the bottom but because of the possibility of long scripts I think the save/load buttons should be at the top? Or maybe folded into the menu bar at the bottom.
Maybe there should be 3 vertical dots at the end and move reshape table and report a bug there (any maybe others?)
So can we add the option to use Claude API keyless for Marty?

Four small things and one large: the provider list widened, the save and load buttons moved into the bottom row, a ⋮ took the rarely-used controls, and Marty gained a keyless Claude.

Is running in the artifact is keyless Claude the default?
[the app's own message, pasted back — 1 line]
I am logged in but for a user that isn't can't we provide a button to open a tab where they can log in?

Made keyless the default inside an artifact, and offered a sign-in link — but only where signing in is what is missing.

But Claude keyless works in the comic chat artifact: https://claude.ai/public/artifacts/cc4d5dc2-f74d-4199-80e4-ca8d83024ba8 - can you read the source code?

[the keyless-call probe output, pasted — 18 lines]

Read the Comic Chat artifact and found the difference: it is a chat artifact, a different frame from this one, and the keyless call lives there.

Once we settle these issues let's wait until I've done testing before pushing changes.
The way the Comic Chat artifact was made is you produced an HTML file that I uploaded to claude.ai and prompt it to copy the file to an artifact.

[the runtime-hooks probe output, pasted — 14 lines]

Probed the frame properly rather than guessing from the presence of window.claude, which here is a capability kernel with no completion in it. The route is chosen by the shape of what is on the page.

📷
I'm confused - the toontalk-3d-artifact.html is too big for claude.ai so should I upload toontalk-3d.html to it?

The packed build is too big for a chat artifact — which is the whole reason the third build exists.

📷
Infinity activities are working.
Instructions refer to named houses which aren't visible (they are on the side of the house)
Maybe the walls should be taller so there is room for text on the front wall above the door.
Activity 4 gave me an idea for the list operation examples - add another team that converts lists to boxes for clarity so both forms of the result are inspectable
I like the "ellipsis" in nest stacks but wonder if there could be a user action that would move where it is so the user can explore any portion of the stack without having a too tall tower
the attached screenshot was how I was holding a house but couldn't set it down as normal but eventually could and don't know what was different - I can't reproduce this
Another user action should be to rotate what one is holding - it would be nice to rotate numbers and stacks of them to see other faces more easily. Do you have an idea what would be a good user action for this?

Houses wear their names on the front and the walls grew to make room; numbers can be turned in the hand; nest piles can be walked through; and the list examples gained a team that shows the answer as a box.

📷
📷
clicking the ...n
run alongside
The rotation left and right is good - the up and down is weird - not sure how good it is and when clicked twice the stack is upside down but not very visible since at first it is under the table and then when moved out only a few elements are visible (see screenshot 2)

Rotating up and down left the thing on its head and half under the table. Kept the turn, added the fix: after every turn the thing rolls to whichever quarter leaves the writing upright.

I forgot to mention the text on the house should have a bigger font

A bigger font for the name on the house.

📷
The arrow keys for a number should always continue to work to keep rotating. Numbers currently have a blank face on the bottom - is there another representation that might make sense? continued fractions? something else?
I loaded reverse. It ran fine but there wasn't the house converting the stack to a box
And as I keep seeing occasionally the robot became small behind the desk as in the screenshot

The arrow keys keep turning a number however far it has gone, and the blank bottom face became the continued fraction — his suggestion, and the right one.

📷
📷
📷
📷
📷
I think we can improve the holding message. Instead of "113 /" it should either be "÷ 113" or "divide by 113". The rest of message is fine for integers with the default + operator but if the user has already constructed a number with an operator it should list the other permitted operators and "say what it does" isn't needed - but if there is room it could mention the arrow keys.
The continued fraction representation should be more graphical (with nested horizontal lines indicating nested fractions like the screenshot from Wikipedia)
Screenshot 4 does the decimal expansion of 355/113 - doesn't it repeat?
" 7 — prime" is good but " 7 is prime" is better
the prime decomposition face is good but screenshot 5 shows it became blank for a large number
I worry that "1 — no primes at all" may be confusing to beginners

Six on the faces of a number: the holding message says ÷ 113 rather than 113 /, the continued fraction is drawn as a staircase of bars, the decimal says how long it repeats, and the factor face stopped going blank on a number too large to factor quickly.

go ahead with list to box

Built the List-to-Box team, and gave it to every list example.

📷
📷
The 3 dots are in the wrong place
Is there a way the user can see a face right side up? Upside down makes sense for rotation - maybe while holding a number and rotating it if the face in front of the user is upside down or rotated the cube is rotated automatically to make it easier to read
screenshot 2 shows a number that was wiggling when the mouse had moved to another screen

Turning a number now leaves the face you asked for the right way up — found from the meshes themselves rather than a table of orientations.

when I ran reverse the robot in front was full size until the very end but the other robot worked while small - the list to box worked fine. When they finished both were small.

The robots that worked at sleeping size were inside houses, and the check for it ran in the world outside, where their names are not known.

📷
continued fraction is better but still not good

Measured the continued fraction against its own face rather than guessing at it: it had been starting under the operation badge and running off the right edge.

📷
📷
43/30 is nearly perfect the 4 is unnecessarily offset 355/113 looks fine
Go ahead and commit after fixing this.
Let’s add to BACK.md the possibility of importing 3D models - you probably know better what the bird API would be like for them.
And since users can drop a saved object or world or load it via the import button, why not enhance those to support any kind of media?
Then generate an HTML for claude.ai to copy into an artifact

The last denominator centres under its bar. Then: 3D models in BACKS.md, one door for every kind of media, and a third build small enough for a chat artifact.

📷
If running in an artifact then the keyless Claude is the best default. But otherwise leaving it in the menu is confusing
When I load the models into the artifact I could see the models behind the login screen. But I can't get past the login screen. Here's the console:

The console had the answer three lines from the bottom: a sandboxed artifact frame refuses form submissions before dispatching the event, so the name card — a form — could never close. Neither dialog needed to be one. And the keyless Claude left the menu where nothing can carry the call.

The published artifact is working fine. I tested it in Firefox and it asked me to log into Claude. One minor thing is that after I logged in I needed to refresh the app for it to know that I was logged in.

Marty checks for himself now: come back to the tab and, if the keyless route sat signed-out, he quietly asks Claude for one word. An answer clears the trouble and says so; silence says nothing.

Can we make an interactive activity sheet based on the 7 activities here: https://toontalk.github.io/tt-wasm/tt-wasm/build/infinity/index.html
Our 7 examples are the "answers" but some students may want to do the activities and be guided to make something like our examples. Access to this new page (or pages) should be via the 3 vertical dots menu. Maybe when inside these activities Marty should be informed of the goal and desired pedagogy.

infinity.html: the seven activity sheets beside a live workshop, the answers demoted to a peek button, and Marty briefed per activity to play the researcher — lead with questions, pairing over counting, never state the conclusion.

The message " stopped: the red parts of its thought no longer match. Dusty can vacuum them away." should mention Mimi the eraser too - probably first
I think it should be possible when training a robot with something on a nest to be able to drop an object on the object that is on the top of the nest - it doesn't allow it and a message appears saying what kinds of things robots can interact with
Also if a robot is trained to manipulate an object then if given a box with that object on a nest it should perform the same operations. Critically if it picks up that object it does not pick up the nest with the object (that is the current behavior).

Ruby (not Mimi — she is the copier) now leads the advice when a thought stops matching; training can drop onto a delivery sitting on a nest; and a robot trained on a bare value reaches THROUGH a nest that arrives instead — with trainedOn, not the thought, as the signal, which a failed first attempt proved.

I trained a robot on [1 | bird] to drop x2 on the 1 and then give the result to the bird. When I ran with a nest with 1 on top instead of the 1 it dropped the x2 on the 1 which resulted in the x2 going to a work spot and the unchanged 1 on the nest being given to the bird
In one of my tests the robot being trained was tiny.
I find that I make mistakes forgetting to turn off Ruby or Dusty. Is there a way for the cursor to change when either of them is active?

Three more: the put side of the nest window (drop x2 straight onto a nested delivery), the tiny robot closed for real — a mini flag set when a transition is decided plus a registry of every robot ever made — and a ring cursor in Dusty's red or Ruby's pink while either is awake.

Try again

A model switch mid-answer; the work carried on.

Everything seems to be working fine. Though I'm unsure if you ever fixed the occasional small robots during training or execution.

Let’s do more planning for BACK.md. I think audio files are clear. This reminds me that we may at some point want to support generated sounds as well. And transformations of sounds.
Regarding images it is mostly position, width, and height. But a 2D element in a 3D world can be awkward to work with. Do you know how others have handled it? Video too
I don’t know much about 3D models. When they have movable parts is that declared in the file? Can a bird API be generated after loading that provides full control of the model?
At some point we should add user settings. One would provide control over tooltips. And maybe the aesthetics of some of the elements - e.g. color of birds and robots. Let’s remember to come back to this.
Another thing to remember for later is 2D boxes (like arrays)
I wonder if “back” is the right metaphor. It suits 2D ToonTalk well but the back of a number cube or house don’t make sense. Maybe objects have control panels that initially only have the bird and nest but users can add working robots/houses. Some user action while holding an object releases its control panel.

Planning round two for BACKS.md: the metaphor itself questioned (a cube spends all six faces — the candidate is a control PANEL), the flatness problem surveyed and answered with the workshop's own tablet, sounds made and remade by the badge gesture, and what a model file declares — the bird API generated by reading it.

Good. I like the idea of extending text pads to images and videos. I guess there are many ways to associate an image with a text pad. Their control panel could have a import button and also receives drops. Also holding a text pad and pasting an image should have the image cover the text pad. Pads can have sub-pads whose coordinates are relative to the containing pad. We should remember to call these "pads" not "text pads" since they are so much more general.

Another thing to remember is the idea that some creations can be exported as web pages. E.g. if Pong is built in ToonTalk it can become a web app. Houses that just do computations could also be compiled to the web.

I'm wonder when we start implementing this if we should do it as a new HTML file name so the released toontalk-3d.html isn't affected

We should support the creation of "anima-gadgets". See https://toontalk.com/behave.tt and https://web.archive.org/web/20081222000240/http://www.ioe.ac.uk/playground/TTLibrary/completelist.htm - read these carefully. An important idea is that when a control panel is placed on a control panel then the inner control panel controls the object of the outer panel. And if an object is placed on a control then its control panel is treated as a sub-panel and the controlled object is re-assigned.

Round three: anima-gadgets read from the sources — behave.tt decoded, the IOE catalogue transcribed whole, Miki's write-up found — and Ken's binding rule recorded: panel-on-panel re-points the inner robots at the outer panel's object. Pads generalised, with sub-pads.

Good idea to "copy today's file to toontalk-3d-v1.html, point index.html at the snapshot until the epic settles, and keep developing in the canonical file under the byte-identical regression harness that already guards every commit."
Can you generate a plan doc please?

PLAN.md: the epic in six stages with acceptance criteria, the Devices notebook moved before behaviours, the library capped at twelve, Pong as the capstone — and the snapshot taken: toontalk-3d-v1.html is the released app, byte-identical, with index.html pointing at it.

Plan looks good
holding-card button is good (+ a key)
panel is a good name
For other stages the recommendations look good and we'll flesh out the ones missing recommendations later.

We need to think about bird and nest "API" documentation. It should be describe the kinds of boxes the bird can process. And why not make it easy for user to copy an example box from the docs to edit and use. Perhaps ToonTalk notebooks are the right format. Perhaps all panels have "info" button (or 2 if bird and nest docs should be separated)

Thanks for finding Miki's paper but I don't know what she meant be "the entire purple rectangle shown"

One more thing to remember - user extensibility using JavaScript. E.g. maybe someone wants to use some API available in most browsers then they should be able to create something (maybe anima-gadget? at least a bird and nest to the API) that can be loaded into ToonTalk 3D

The two Stage-0 decisions landed — the name is panel, the gesture is the holding-card button plus a key — and the info notebook: a panel's documentation is live example boxes you copy out and send. Plus native panels for wrapping browser APIs, marked for after the epic.

Would it best for Fable, Opus, or Sonnet to start implementing this? What effort level?

Staffing by task shape: strongest model at high effort for stages 1, 2 and 6, a fast one at medium for 3–5, the regression gate as model-insurance either way.

sure record it and start with the first stage

And the epic began. Stage 0: the harness became tests/regress.html with pinned goldens. Stage 1, same day: every thing can carry a panel — a tray on the bench, a room with no walls — opened by the gear on the holding card, glued through saving, filing and Mimi, closed by its brass knob. All nine acceptance checks passed.

No tooltips for pads or panels. Both pointing to and holding something
I trained a robot and when I clicked to stop training an unrelated panel disappeared.
I can't pick up panels. Nor can I pick up items dropped on a panel. I should be able to resize them.
Panels overlap is odd ways and the text is placed at a location that makes it hard to read (see screenshot)
Once again I got a tiny robot by dropping a number on a fresh robot (screenshot 2). But seems to happen randomly.
screenshot 3 - Ruby can't erase the box in the robot's thought bubble.
Import doesn't work - an example world file attached
Notebook has page turning buttons duplicated (screenshot 4)

Ken's first panel test found eight. The doubled notebook arrows and the dead import were one bug (every save wrote the main notebook into the file); the disappearing panel was the training rewind rebuilding things from specs that knew nothing of panels; and Ruby could not erase a box because its shell hides behind its own contents — the erase ladder climbs now.

panel resize handles aren't accessible - trying to use them just picks up the panel

tooltip for dropping the robot incorrect (screenshot 1)

save world and load worked

robot worked on panel when visible. But I returned the panel to its owner, switched from 1 to instant and then back to 1 and the robot had only run 2 rounds.

Round two: a closed panel FROZE its robot — it closes live now, invisible on the bench where the scheduler already finds it, measured 81 rounds at closing and 1281 a few seconds later. Plus hittable studs and the tiny-robot trap learning to log its stack.

📷
📷
The tooltip says I pointing to the corner stud but nothing happens when I try to drag it. But while trying at one point I did manage to resize but unsure what was different

It is not clear how to activate the robot on a panel - I did it but also some attempts did nothing. I was able verify that the robot ran at instant speed inside an object.

screenshot 2 shows when I added a second robot to the panel one of the robots became extremely tiny (probably the one that was there already - I should have named them)

I managed to resize a panel but nothing happened and then it resized - no gradual change

When I pick up an object from the panel it appears a good distance away (maybe the robot's work area) and flies to the cursor.

Round three: resize follows the pointer (he tried to drag — the click-then-click was unguessable), panels grew the same lever a house has, a second robot JOINS the team instead of shrinking to a fortieth of life, and taken things rise from where they stood.

📷
screenshot 1 shows pointing to a number being updated by the robot and it is working fine. the tooltip shows the current value but is updated only if the mouse is moved - if the thing being point to is changing then a few times a second the tooltip should be updated
Yes let's move on to the next stage

The tooltip re-reads itself while a robot changes what you point at, and Ken said: on to Stage 2.

A tiny robot being trained:
[the tiny-robot stack trace, pasted — 9 lines]

The stack trace that ended three days of hunting: the tiny robot was the HOVER WIGGLE, capturing a mini's scale when the pointer arrived and stamping it back on the grown robot — every tablet tap a motionless pointer. The wiggle defers to the truth now.

📷
📷
📷
The robot correctly stopped since the pad wasn't blank. The issue is that nothing was red to indicate a mismatch. Also when a text pad has text the angle of view in the thought bubble makes it impossible to read. Maybe in a thought bubble text pads should be rotated to become readable. This is an issue for boxes as well (screenshot 3).

A mismatched pad never turned red — flagMismatch skipped every multi-material mesh, and a pad is exactly that. And pads in thought bubbles stand up like cards on an easel, in boxes and on pans too.

📷
I trained a robot with a box with a number and a bird to the number to increment the number and give a copy to the bird. The bird's number updated appropriately. I don't understand why the number's nest ended up copies of its value at different times.

It is hard to toggle the switch on houses when the house is wiggling. Make them wiggle much less. Panels as well.

I think birds and nests connected to an object should have tooltips that indicate this

The tower of numbers was the event nest doing its job — a change log — but the confusion earned labels and tooltips: live birds and event nests say whose they are, and houses barely wiggle now.

I'm thinking the event nest should not be on panels by default. Like event listeners in JavaScript you need to send a message to obtain one. So [listen | reply-bird] given to an object's bird would give the reply-bird the event nest. I think we want to support specialized event nests. So an image bird might be given [listen | position | reply-bird] to obtain a nest that receives position updates.

When I trained a robot to give a number's bird another number it flew to its number and updated it. When we are in the thought bubble of a robot we are seeing its "imagination". So any changes it makes to the external world should be restored after leaving the thought bubble.

Two design corrections. Event nests are OBTAINED, not furnished: [listen | reply-bird] subscribes, with room for channels like [listen | position | bird]. And the thought bubble is imagination again — a live delivery made in training showed, then rewound.

working - go ahead with the next parts

Stage 2 landed whole. The info notebook (an i-plaque, Miki's layout, the +10 copied off a page, edited to +7, delivered — 5 became 12); the gauge ringing one lap and stopping on the echo rule; and the account whose teller is simply gone — two rooms depositing at once onto a live balance that lands on exactly 250. Eleven goldens.

📷
Pads with lots of text are very hard to read. They should be resizable and the text should scale.

Control-c to copy what is held should be part of the tooltip

the info button is hard to see against the panel

When I trained a robot on a scale where one of the numbers was live after finishing and stopping the number was no longer live.

Thought bubble matching for scales should include what is in the pans

left and right arrow keys should change the pages when pointing to a notebook

I tried the live bank account and it worked but then it stopped working. Neither switch did anything.

Seven at once. Pads grew a size of their own (Ctrl+arrows, the text scaling with the tablet), the info plaque got a rim it could be seen against, and the live number survived training — the rewind had been stripping its lid. Scale thoughts read their pans. And the account had stopped because a closed panel took its robot with it.

I intended to erase a number in a pan in a thought bubble and accidentally erased the entire scale. There is no visual clue as to what will be erased.

When a scale cannot determine which is 'heavier' (e.g. a number and a text) it should tip up and down and not match any other scale

The generic advice at the end of the text pad should start after a blank line

It should say the current value is given to that bird to deliver to its nest.

📷
Screenshot 2 shows the 'holding …' message that prevents a mouse click — maybe it should also move to the top

While control-upper arrow works that is not kid-friendly. Why not when anything is held the menu for rotation and obtaining the panel has options for bigger and smaller. The size handles on panels can go away then.

Ruby now outlines exactly what she will take before she takes it. An undecidable scale rocks and matches nothing, which is the honest answer. And the holding card moved out of the way and grew bigger/smaller buttons, so the panel's corner studs could go.

Holding panel is broken and at the wrong place

The holding card lived inside #bottom, whose transform captures fixed positioning — so 'fixed' meant fixed to a bar that moves. It is a child of the body now.

📷
The problem is that the held item is far back when its size is changed. Screenshot 1 shows it before, 2 after making it bigger. And then when dropped (screenshot 3) it grows even bigger which is clearly wrong.

A pad's size lives in its geometry, and the hand was applying it a second time as a node scale — so every put-down squared it. Text pads are out of the node-scale path entirely now.

Does the bottom menu bar need to be part of the world - it too prevents drops. And held items move to an odd place when the cursor is over that menu bar. Or maybe it should also move to the top so it is out of the way

The bar left the world: a reserved strip below the canvas, with the NDC computed from the canvas rect rather than the window, so nothing you hold lurches when the pointer crosses it.

go ahead with stage 3. By the way maybe everything should wiggle less - like houses and panels

Stage 3 opened, and everything that wiggles wiggles a third as much.

when I click on the ... in the holding panel I see the full thing upside down. It isn't obvious that clicking it again dismisses it. Why not any click dismisses it?

You should be able to return anything to the notebook page it came from if it wasn't altered.

I thought left and right arrow keys was another way to flip notebook pages - doesn't seem to work

Boxes for built in messages should have labels for the holes

When I dropped 2 on 1/2 in the box it didn't change size to fit

The speakers don't look good and are too close in color to the pedestals.

I can't obtain a panel for a sound object

The held thing reads upright because its basis is built outright now rather than composed from a lookAt and a quarter turn. The arrows did work — a focused Speed control had been eating them silently, and a click on the world takes the keyboard back. Message boxes wear labelled holes, and the speakers left the pedestals' colour behind.

sounds are a bit better but too much like other things. Maybe a bit like the photo I pasted (but don't copy it)
📷
When I dropped a 2 and the 1/2 the number blocks became their labels
And why is the shape label smaller than the other labels
When I clicked to return a panel to its object it animated away but it should animate towards its object as it shrinks
Dusty should be able to vacuum up a notebook if the click is on the spine.
Dusty can vacuum away a page but it doesn't animate when doing so
I dropped a WAV file and it works fine. It shouldn't play just because I picked it up. Maybe we should intro the ToonTalk convention that the space bar turns things on. Should work for houses and panels too. In ToonTalk '.' stopped them since it is often called 'stop'.
Let's start a folder under examples for sounds.
When importing media they appear in the center of the desk rather than where they were dropped.
The info notebook for a recorded sound still suggests sending freq, sec, shape which doesn't make sense for recorded sounds
When I dropped a box on panel it became very tiny

Ten, and the two that mattered most were conventions. SPACE turns on what is in your hand or under the pointer and “.” stops it — so picking a sound up no longer startles you by playing it. And the speaker became a walnut cabinet with a black baffle, because what says 'speaker' before any colour does is a wooden box with a dark face. Hole labels are the box's own plaques now (they had been overwriting the numbers' faces), a returning panel folds toward the thing it belongs to, Dusty flies to a page before clearing it, media lands where you dropped it, a recording's notebook stops offering a recipe it cannot use, and a box dropped on a panel is three times the size it was.

And another folder of examples for images

Two folders, six worlds, and two of them joined the gate. sounds/: tones (where a sound comes from), transforms (×−1 reverses it — the same minus sign that makes a number subtract, on a thing whose axis is time), melody (a robot that sings a queue of numbers, C major, a note a round). images/: pictures, album, and naming — six robots that dispatch on the PICTURE in their thought, which needed no new machinery at all, only the fact that a picture is a pad. The suite is thirteen worlds.

📷📷📷📷
While a full size robot is running the user should be able to do most everything except run or train another robot. Can pick up things and combine them while the robot is running behind the desk.

The overlapping labels in screenshot 1 flicker when pointed to I guess which is on top is alternating. They shouldn't overlap

The labels in the examples have labels that can't be removed or edited (e.g. “the tune”)

I picked up faster but couldn't put it back where it was

If subpictures (screenshot 3) are to be usable in games then the subpicture should have no depth. Think of the ball in Pong.

The naming pictures example reveals that teams need to be animated better. When the first robot doesn't match it its thought bubble should highlight was isn't matching and then it should move to the side and the next robot should “try”. The mismatching robots form a queue until one matches and when that robot is finished the team re-forms. Or else all fail and they queue up. First one to doze causes the team to stop until that robot wakes up.

Is there an invisible door near Marty - he's jumping up and down and the tooltip indicates a door is there.

Seven, and the first one moved a wall. The workshop no longer freezes while a robot runs, because the robot’s claw stopped being your hand: the two were always separate nodes in the scene and the same variable in the code, and splitting them is the whole of it. You can now take, drop, join and type while a robot works behind the desk — measured 7 + 5 = 12 on the table mid-run, with the same run going on to answer 120. Its own area still says no, by name. Teams take turns visibly now: each robot in front of the winner steps up, shows its thought with the parts that do not fit in red, shakes its head and goes to the back — and the first one to doze stops the team, rather than being stepped around. A plaque is never wider than the thing it names (three of them over 0.15 holes had been overlapping two deep, which is what flickered); sounds, scales and notebooks can be named and un-named; a pad riding on a pad is a flat sprite with no paper and no border, which is a Pong ball; anything you pick up can be put back exactly where it was, because aiming at the gap it left never could work. And yes — the way out of a house is a 1.6-metre door standing invisible right where Marty does. three.js stopped skipping invisible objects years ago, so it had been quietly taking every click and tooltip meant for him.

A common thing in ToonTalk is to use Dusty to remove a subpicture to explore it in isolation. Dusty can remove subpictures but it doesn't have a way to spit out what it has sucked up. I'm reluctant to add a button on Dusty and have keyboard shortcuts but I can't think of good alternatives.

The ToonTalk idea that dropping a number on a text pad changes the first or last character probably was a bad idea. And we want to add numbers to pads - e.g. for displaying the score. Let's make them act like subpictures when dropped on a pad

Robot team animation is pretty good but in the screenshot triangle isn't running but is in the way of the robot who is to the right of him. I think the robot behind the active robot should be moved back and smaller so there is no confusion

I'm assuming the heart or the word “heart” are subpictures and yet Dusty vacuums up the entire thing. And I think only the subpicture should wiggle if it is selected by Dusty or Ruby.

Screenshot 3 has a thought bubble with no visible robot. Imported album example.

The import button should also support the import of images and sounds (and txt files as pads) TXT should be droppable as well.

Pointing to something in a notebook should produce the usual tooltip

I'm unclear how to create a picture like those in the album example. I now we can combine text and subpictures but how can a user create the white text on gray at the bottom?

Eight. The one Ken could not see an answer to needed no control at all: what Dusty swallows now rides ON HIS HEAD, where you can see it, and the workshop already has a rule for a thing you can see — click it and it is in your hand. No button, no shortcut. He keeps the last six; older ones fall out, which is what a vacuum is for. A number dropped on a pad RIDES on it now, for a score on a field, and the letter-shift it displaced is gone with Ken’s blessing. The team animation had a real bug hiding in it: takeTheFloor decided who was standing where AT CALL TIME, and the new try-and-fail queue calls it five times before any of them plays, so every swap in a round was computed against the same stale answer and two robots ended up full size on one spot. It decides in start() now, and the ones waiting stand in a row well behind the desk. The bubble over nothing was the borrowed thought a team run leaves in condShow, which loading a world did not clear. Import and drop are one door for pictures, sounds, TEXT FILES as pads, saved things and saved worlds. Notebook pages answer with what is filed on them. And two answers rather than fixes: Dusty already takes only the subpicture and only the subpicture wiggles — the album’s hearts are not subpictures at all, they are pads with a picture on the face and the pad’s own writing across the foot, which is also the whole of how you make one: hold it and type. (Pointing at a picture says so now.) One thing the wiggle WAS getting wrong: it rescaled uniformly, standing a flat sub-pad back up into a slab every time the pointer crossed it.

📷📷📷
Regarding 8 this feels too special purpose. There should be a generic way to create the gray rectangle with white text that can be dropped on a picture pad. When text pads have an API one should eventually be able to specify the background color, the text color, the font, and of course the width and height. Then a robot could be trained to create these kinds of labels and drop them on a picture pad. Numbers should also have an appearance API like text. This isn't high priority if there are other tasks waiting for you.

pointing to a text pad produces the nice tooltip in the screenshot but when pointing to the same text pad in a notebook the tooltip is abbreviated (screenshot 2)

The tooltip in screenshot 3 could be better. The first part can be expanded and the part about training is only appropriate when hovering over an untrained robot

Your solution for Dusty is neat and I saw it working when a robot used Dusty. But when I used Dusty to vacuum a picture off a notebook I didn't see the picture on top of him.

When a number is added to a pad it should just display the value (not the operator and red square) and should not extend out beyond the edges of its parent.

He was right that captioning-by-typing was too special-purpose, and the correction is the better feature: HOW A THING IS PAINTED IS DATA. [set | background | grey], [set | colour | white], [set | font | sans], [set | width | 2], [set | height | 1/3] — sent to the thing’s own bird, exactly as [query | bird] already is, and every one of them a real box on a page of its info notebook you can take out and edit. So a label is not a feature, it is four messages, and a robot can be shown how to make one. Numbers take background, colour and font too. A pad’s face is drawn in fractions of itself now rather than in a fixed 512 by 384, which is what lets it be two wide and a third high without the writing coming out stretched. Verified end to end through the documented path: info notebook → take the box off the page → give it to the bird → a grey label with white sans writing, which then rides on a picture. The rest: Dusty took a picture off a notebook page and it never appeared on his head, because the page-clear re-renders the notebook a beat later and rendering a notebook throws away every node it drew last time — including the one by then in his bag. A pad filed on a page now gets the same tooltip it gets on the table, quoted whole and paged with Tab, out of one shared reader. The workbench says what it is FOR, and mentions robots only when there is a robot about to mean anything. And a riding number shows its value and nothing else — no badge, no frame — and is clamped by its own half-width, since u and v had been clamped as POINTS and half of a thing sat outside the pad.

after finishing that go ahead with the next stage

Stage 4, the Devices notebook. The workshop’s senses are NESTS: a keyboard nest that takes a pad per key press, a pointer nest holding [across | away] in the table’s own steps, and a press nest. Nothing new had to be invented — a robot facing a bare nest has dozed since the first list example, so a robot given a keyboard nest wakes once per key and waits in between. Waiting for input is not a feature; it is what dozing already was. They are read-only BY CONSTRUCTION rather than by permission: each arrives with no egg, and a bird is the only way anything is ever put on a nest, so there is no rule to enforce. Two examples stand as the acceptance: keys, where the Scribe joins each key onto a pad and read “Hello Ken!” after ten dispatched key events, and pointer, a gauge whose two numbers tracked three pointer positions. One thing had to give way: an empty eggless nest lifted off a notebook page is replaced with a fresh one — which is what makes the blank-nest page useful and which was costing a device nest the guid that makes it a device.

while I do some testing go on to stage 5

Stage 5, anima-gadgets, most of the way. First the piece everything else needed: WHERE A THING IS became data, in the same grammar as its appearance — [set | across | 1/2], [move | position | [dx|dz]], [query | position | bird], and channels to doze on: position, edge, and touch, which hands you a live bird to whatever ran into you. Then a BEHAVIOUR: a pad whose panel carries robots that speak about “my thing” through a live bird. Binding is not editing — drop it on something and one bird is re-pointed and nothing else changes at all (measured: 8 references for the bouncing gadget, and not a step or a thought among them). Self-demonstration then costs nothing, because an unbound gadget’s bird points at the gadget: set it down, press SPACE, and it does its thing to itself. The acceptance ran: a star, the bouncing gadget dropped on it, SPACE — out to 1.24, turn, back to −1.17, turn again, with no training anywhere. Six of the twelve are on the shelf; the other six want a size message or arithmetic on a touch, and are next. One design decision was forced and is worth keeping: the EDGE is a reading and not an event, because a team member facing an empty nest dozes and a dozing member stops the team — an edge event would have stopped the very robot doing the moving. A reading is never empty, so the bouncer is three robots that differ only in the word they expect.

When I tried following at speed 8 I see screenshot 1 and the pad doesn’t move but it works fine at “instant” speed

When I tried the library anima gadgets when I turned them on their panel appeared - screenshot 2

pointer world at 8x the robot after being given the box moved very slowly - something else must have been keeping the CPU busy

The third one was the real find, and it was measurable: THIRTEEN GPU TEXTURES PER POINTER READING, never released — about a hundred and forty a second while your hand moves. removeFromParent does not let go of a painted canvas, so a reading replaced a tenth of a second later left everything it was drawn with on the card. A thing the workshop throws away for good now releases its canvases, with the eight shared world maps marked so they are never disposed by mistake; after, the count sat flat at 97. Switching a gadget on folds its panel away rather than throwing it open — the robots keep working out of sight, which is the state a panel already had for a house with work still in it. And “not standing on the table” could not be reproduced at any speed, so instead of guessing, the refusal now says WHICH of the other places the thing is in — in your hand, in the claw, in a hole, on the robot’s desk — and logs the parent chain, the mode and the speed, so the next sighting arrives with its own evidence.

the bug with the following.world is gone

library.world no longer brings out the panels but if I turn on more than one it becomes very slow overall and some gadgets stop moving when another is turned on

pointer.world still animates very jerkily - as if the frame rate as 1 or 2 fps I see it freeze frequently for about a second - even Marty’s bouncing stops

The bench is GLOBAL — a running world can see the outer table from inside, which is deliberate and is how a house finds the houses in its own box. But it means that while panel A had the world pushed, its nested-rooms loop found panels B, C and D sitting on the table beside it and ran them AS IF THEY WERE INSIDE IT: depth one, two, three, each taking a forty-round batch. Measured before: a single processDirtyRooms took 1.2 to 5.6 SECONDS and climbing. Two lines fix it. A panel’s turn is ONE ROUND wherever it is reached from — it is a ticker, not a batch worker — and a room marks the frame it ran in at the top of its own turn rather than in the caller, so a nested find cannot hand a sibling a second turn in the same frame. Then the frame itself got protected: behaviours share eight milliseconds of it, least-recently-run first, so whoever is squeezed out is first in the queue next frame — which is exactly what “some of them stop when I turn another on” was. Two things a ticker must not do sixty times a second were coalesced: rebuilding the whole side panel (now at most eight times a second) and re-fitting the contents of a world nothing has grown in (every eighth round). Median with six behaviours going: 15 ms.

can you try to make the pong game

It plays. The TABLE IS THE COURT — three of its walls are the table’s own edges and the fourth is yours — and the ball, the bat and the counter are three ordinary things standing on it. The ball and the bat each carry their own program on their own panel, so two programs run at once, which is what makes it a game rather than a demonstration. The ball’s team is six robots that differ only in what they expect in two holes: far or near wall, flip the away step; left wall, flip the across step; right wall, give the counter’s bird a +1 and start again in the middle; touching a thing, flip the across step; anything else, fly. Nothing anywhere knows the game is Pong, and no engine work was done for it: [move | across | n] and the edge reading came from stage 5, the pointer device from stage 4, a badged number given to a bird from stage 2, and [set | width | n] from stage 3 — which is the whole of why the bat is a bat and the ball is a ball. Three general bugs had to go first, and all three were found by measuring rather than by thinking. TOUCH became a reading like the edge, for the same reason: an event leaves the nest empty, an empty nest makes a team member doze, and a dozing member stops the member doing the moving — so a ball that bounces off a bat could not be written at all. AUTO-RUN turned out to belong to the table only: mail landing in a running robot’s own box armed another round, and inside a panel that round ran from inside the first round’s own queue, outside the scheduler, outside the Rounds limit and outside the frame budget — measured at 594 extra rounds in ONE FRAME, sixteen seconds of it, which is exactly what “it freezes for about a second” looks like from outside. And the EDGE reading clamped with a strict greater-than, so only the move that was refused said “right”; a round sends two messages and the second was not refused, so the reading was back to “none” before the round that would have acted on it began — a robot whose thought asked for the right-hand wall never once saw it. Verified by driving the frame clock and the pointer together: a player who tracks the ball saves it twice and misses nothing; a player who walks away is past at frame 675, the counter goes to 1, and the ball starts again in the middle.

pong.tt (attached)
We’ll keep your version of Pong but can we also make one like the original (attached).

Your pong game works (but the “ball” behaves oddly when touching the text pads). Yes, the player can remove them. The number that is the score should at least have a label.

Can you clarify how dozing robots are woken up. As I recall in original ToonTalk when robot dozes it registers with what it is waiting on (typically a nest receiving something) but it could be a sensor changing value. There is no runtime penalty for having a huge number of dozing robots. Is this how you did it?

The .tt file is a zip with the object in XML, and reading it settled three things at once. The original is not played on the table: the whole game is a green rectangle and the ball and the bat ride on it as PICTURES ON A PICTURE. Its ball carries SpeedToRight and SpeedToTop as properties of the picture — it moves on the world’s clock, and its robots only change the speed. And its collision sensors are per axis, “Right Collide?” and “Up Collide?”, one Bounce robot each. So: a pad can be a FIELD (a thing riding on a pad has a place of its own, in that pad’s own steps, and “the edge” means the edge of whatever you are standing on — which is why nothing on the table is in the ball’s way and nothing needs clearing first); a thing can have a SPEED, with an empty hole meaning “leave that one alone”, so turning a ball round is one message with no arithmetic in it; and the touching reading is a box of two, what I ran into and WHICH SIDE of me it is on. That last one is Ken’s odd ball: with only “what”, the single possible answer is to turn round one fixed way, so a ball meeting the flat of a pad slid along it turning round every round. The first Pong takes the same fix, plus two rules learned from it — ask about the WALLS first, because a wall pins you, and after a collision SET a direction rather than flip one, because flipping reverses whatever you were doing, which half the time is back into the thing you just hit. Measured: 900 frames loose in an uncleared court, never once stuck. The score wears its name. And measuring the new game found what has been making everything slow: THOUGHT BUBBLES BUILT FOR ROBOTS NOBODY CAN SEE — a bubble is real geometry with a painted canvas per part of the thought, and a behaviour takes a round every frame. 52 canvases and 36 ms a frame before; 0.2 canvases and 1 ms after. On the dozing question the honest answer is no: a dozing robot goes into one global set and every delivery walks all of them, re-reading each work box and matching it against every team member. It has not bitten because worlds have a handful of dozers, but it is O(dozing robots) per delivery where the original was O(1), and the fix is the original’s — register the waiter against the guid of the nest it is dozing on, which enterWaiting already works out in order to say which nest it is waiting on.

📷
Let’s remember that when we implement long-distance birds we can make a 2-player version of Pong

Classic Pong has the ball moving but instead of bouncing off the edge nearest the camera it hugs the edge until reaching the corner where it stops
Also it should be on the closer side of the table to avoid overlap with the notebook.
I was able to pick up the ball and paddle (only Dusty should be able to remove them) but then dropping them back on the green pad did not restore them.
The paddle never moved

Regarding set speed was this a primitive in ToonTalk? Need it be in ToonTalk 3D? We should return to this later

The hug, the stop and the motionless paddle were ONE bug, and it was a number. ROUNDS defaults to 100 and its control tops out at 10000; a behaviour takes a round every frame, so a switched-on gadget stopped after a hundred frames — under two seconds. The ball then kept moving, because with a speed it needs no robot for that, and with nobody left to turn it round it ran into the near wall, slid along it and parked in the corner. The bat stopped in the same second. Rounds is the right idea for a robot you have handed a box to — its own message says so, “the Rounds limit, not its condition” — and the wrong idea for a ticker: a behaviour is switched on with SPACE and off with “.” and that is the whole of its life. Two smaller things fell out of the same report: holding something in your hand had been stopping every behaviour on the table (the same mistake as freezing the workshop while a robot runs, which makes a game unplayable the moment you reach for anything), and a panel whose turn was interrupted was stranded for good by a flag that no longer gets cleared — a turn cannot outlive its frame, so now it is. The pitch moved to the near half: measured, the notebook stands at z 1.05 to 1.61, so the field runs 1.66 to 2.34 and its middle is exactly 2 steps back, which is a nicer number for the bat to subtract than the 9/5 it had. And riders belong to Dusty now, as in ToonTalk: a scene should not come apart by being pointed at. Putting one BACK was refused by a rule that is there on purpose — a behaviour dropped on a thing binds, asked before every other rule, because a behaviour is a pad and a pad landing on a pad would ride instead. Pong’s ball is both at once. The tie cannot be settled by looking at the two things, since both readings are legitimate; it can be settled by looking at where the thing came from, so detach now remembers a pad it was taken off — which also gives riders “put it back”, which they never had.

I think we should get rid of the maximum rounds and replace it with a toggle for pause/resume everything. (Or stop/run)

I’m not sure I understand the problem with putting the paddle or ball back where it was. A user might develop them independently and then add them to a picture pad

Also there is some weird interference between displaying the green playing field and the paddle in screenshot 1

Later let’s discuss whether speed gauges could be user-built and then used in the ball.

Pong still isn’t working - paddle doesn’t move and ball hugs and gets stuck in the corner

Rounds is GONE — out of the bar, out of the engine — and one ⏸ Pause button holds the whole world still, mid-stride. Every RUN pad in the examples now says the true thing about how its own run ends: a finite job ends itself, a room has its lever, a behaviour has SPACE and “.”, and everything at once has Pause. The stuck ball had a second cause beyond Rounds, and it was a design fault: the ball’s SPEED CAME ALIVE AT LOAD, before any robot was awake to turn it — so it crossed the pitch unattended, hugged the near wall, and parked in the corner, which is exactly what Ken watched. A gadget’s speed is part of its behaviour now: SPACE starts robots and motion together, “.” stops both. And a confession: two days of “verified at Instant” had been verifying a path no user runs, because the harness’s speed(‘instant’) set the global speed to the STRING. The test driver is now a copy of the animation loop’s own body, gates included, so a gate bug must fail in the tests too — and under the faithful driver the ball stands still until SPACE, bounces continuously with no Rounds anywhere, misses count and re-serve, and Pause freezes and releases everything. On put-back Ken was right and the special case dissolved into a rule: a behaviour dropped mid-pad RIDES, part of the scene; on a pad’s edge, or on anything that is not a pad, it BINDS — the same zones that already decide join-versus-ride for plain pads. The stripes were z-fighting, a flat rider flush on a flat field: riders sit three millimetres prouder now and their faces pull toward the camera in depth. Speed gauges — user-built, wired to a thing’s speed the way the original’s sensors were wired to a picture’s properties — noted in BACKS.md to discuss before Stage 6: that is the road on which set-speed stops being a primitive and becomes a convenience over sensors.

When I load classic Pong and point to it and press space the open file dialog appears - when I cancel that I still can’t start it. When I click space I see the import file button highlight. And if the last click was run/pause then a space toggles that button

The keyboard belonged to the last button he pressed. He loaded the world with IMPORT FILE; a browser leaves a clicked button focused, and space on a focused button activates it — so his space went to Import, not to the ball, and after using Pause it went to Pause. There was half a guard for this already: clicking the CANVAS took the keyboard back. But pointing at a thing and pressing a key involves no click at all, which is exactly the gesture the whole space convention rests on, so the guard never once fired where it mattered. Two rules now. A button hands the keyboard back the moment its own click handler is done — captured so a handler that stops propagation cannot escape it, deferred a tick so the handler runs first, only if the button still holds focus (the on-screen keyboard deliberately passes it on), and never when the click came from the keyboard itself, so tabbing still works. And while you are genuinely typing in a field — Marty’s box, a robot’s name — the workshop’s own keys stay out of it. Worth recording what this was hiding: for two rounds every symptom Ken reported was consistent with the behaviours being broken, and twice they were. This time they were fine and the key simply never reached them.

📷
I can play the game now. But typing space to the game should start up all its parts. And “.” should stop them.
When I missed the score became as in the screenshot - no longer digits

A pad with things riding on it is a SCENE now: SPACE on the pad switches on every behaviour standing on it, all the way down, and “.” stops the lot. The pitch is the game and the ball and the bat are its parts — nobody should have to point at four millimetres of rainbow to start Pong. A lone behaviour is unchanged and still says its own piece. The score was a sharper find: setThingLabel hangs a plaque with a thing’s NAME and keeps that name in userData.label — the same field for a nest, a bird, a box, a sound. But a NUMBER also read userData.label for something else entirely: text to paint on its faces INSTEAD of its digits, which exists for exactly one caller, the “?” of an “any number” wildcard in a thought bubble. So naming the counter “misses” armed a trap: the plaque appeared and the digits stayed, because naming a number does not repaint it — and then the first +1 arrived, setValue redrew the faces, and every one of them said “misses”. Which is precisely why it looked right until the moment it mattered. The same mistake was caught once before, in round 9, when hole labels were overwriting the numbers standing in them. Two meanings, two fields; and naming a number repaints it, so its plaque and its digits can never disagree again. Naming the pitch then turned up one more: a plaque on a big pad stood in the middle of it, in front of the game. Nests had solved that already — flat, just past the near edge, like a museum label — and a field is named the same way for the same reason.

I think there needs to be a way to make any pad full screen straight on. I tried holding it and clicking on the holding ... message and the problem was that the game is too wide so I only saw green. And space was added to its label.
So I think we need another way to play games or apps that are on pads

Both halves of that were one mistake of ours: HOLDING a pad is for reading it and typing on it — which is exactly why his space went into the label — and the reading pose is a fixed size that a pitch three times wider than a tablet overflows. A game on a pad is not something you hold; it is something you look at. So point at any pad and press ENTER and the camera goes and looks straight down at it, framed so the whole face fits the window however it is shaped; ESCAPE comes back to the view you left. The important part is what it is NOT: not a screen, not an overlay, not a second renderer, but the workshop’s own camera, moved — so the pointer device still reads where your hand is and the bat still follows it, SPACE and “.” still switch things on and off under the pointer, Dusty still takes a ball off the board, and no robot ever knew anything happened. Measured: a 2.856 by 0.68 pitch fits inside 3.08 by 1.54 on a wide window and 3.08 by 3.97 on a narrow one, and an ordinary tablet fills the screen from 0.65 above. But the round’s real find came out of shipping it. THE SYNTAX GATE HAD NEVER WORKED. Every patch here is checked by extracting the app’s script block and running node --check on it — and it reported ok on a file whose main block had an invalid unicode escape that stopped the app booting at all. The cause is the EXTENSION: the block is a module, and node given a .js file parses it as CommonJS, hits the import, and falls back to a detection pass that returns success without a strict parse. As .mjs the same bytes fail instantly, pointing at the character. The gate now writes .mjs, extracts and checks in ONE process (the two-command form could check a stale extract), asserts the block it parsed is the one holding the app, and says how many characters it looked at — proved by re-introducing the exact escape that got through.

📷
Several problems. The tooltips and the corner panel get in the way. The entire game wiggles since the mouse is over it. The cursor shouldn’t be visible while over the game.

Also the game should be taller. We can change the size of objects but not their width or height independently.

I was able to add the score to the game but the ball bounced off it. Not sure what is a good way to deal with this in a general way.

Escape returned to normal twice and then stopped working.

The cards, the tooltips, the wiggle and the cursor were one thing: the workshop’s furniture is built for a workshop, and looking straight at a pad is PLAYING. So playing is a mode now — the cards and the tooltip go, nothing wiggles (a whole scene shaking under the pointer acknowledges nothing), the cursor is hidden, and only the bar stays, because Pause lives there. Escape failing after two goes was a real bug and a bad one: coming back was driven by a DISTANCE TEST, so anything that stopped the camera converging stranded the mode ON with the orbit controls disabled — a workshop you cannot move — and pressing Enter again mid-flight saved the half-way pose as “the workshop”, after which Escape had nowhere to go back to. It runs on a clock now, 0 to 1 and back, which always arrives. On the score, the general answer is the one everything else here already uses: whether a thing is in the way is DATA. [set | solid | no] makes it scenery and things pass straight through; solid is the default and has to be, since that is what makes a ball bounce off a bat. Measured: the ball crosses the counter without a change of speed and still turns at the bat. Ctrl with the four arrows now shapes a pad — left and right its width, up and down its height — setting the same two properties the messages set. And the pitch is a proper board at last: 6 by 3.2 tablets instead of 8.4 by 2, which is 2.04 by 1.088, close to the original’s proportions instead of a letterbox, standing left of centre so it never touches the notebook.

📷
why is there that line through the score and 2 red dashes at the bottom?

Because a number is a CUBE. Six painted planes stuck to its sides — front, top, back, left, right, bottom — since on the table it is a thing you turn over to read six ways: the value, the words, the scientific form, the grouped digits, the continued fraction. Riding on a pad it is squashed to seven per cent of its height and the five faces that are not the top squash with it, each becoming a sliver standing on edge. The FRONT one is the line across the score, and the red marks under it are the top slice of the digit painted on it. A bare number — one riding, a reading rather than a tool — now shows its top face and nothing else, which is exactly what a pad riding on a pad has always done. Its NAME needed the same: a plaque is hung on a thing standing on the table, and it was being squashed into a sliver of its own; a thing riding in a scene is part of the scene, and pointing at it still says what it is called. The shape of this bug is worth remembering, because it will recur: anything with real thickness goes wrong when it is flattened to ride. Pads and numbers are handled now; sounds, dice, scales and boxes are not, and the first one dropped on a field will show the same slivers.

When the user or a robot being trained vacuums we should keep the ability to grab the last thing vacuumed from the top of Dusty. But when robots are running it should not put anything on Dusty.

The pointer nest has a box with 2 numbers. The label on the box is very tiny and hard to read.

I tried your Pong on a desk and after a minute or two is went slower and slower. A memory leak? Some unnecessary computations?

A memory leak, and bisection found it in three measurements: the ball alone, textures flat at 77; pointer readings arriving with nothing switched on, flat at 171; pointer readings AND the bat’s robot, 212 then 232 — twenty every 250 frames, with the scene’s object count flat at 1495 throughout, which is the definition of it. That is about five a second in real play: six hundred in the two minutes Ken gave it. The culprit is one line, in COMBINING NUMBERS. When a number is dropped on a number the arriving one shrinks into the target and the animation ends with removeFromParent and nothing else — and a number carries five or six painted faces, which removeFromParent does not hand back to the card. On the table you combine numbers a few times a minute and nobody noticed in three months; the bat drops a -7/4 on the pointer’s reading ten times a second. Same mistake as the sensor readings weeks ago, same fix: disposeThing. Flat at 84 across 2500 frames afterwards. A second disposal went in on the way — a message that has been acted on is dropped by a dozen lines in the handlers and none of them disposed it either; it is done once now at the one door every message goes through, in a finally so it happens however the handler returns, and after it, since a [query | bird] pulls the reply bird out of the box. Dusty’s bag is an UNDO and not a cupboard, so a robot REPLAYING its lesson no longer fills it — it made no gesture, so there is nothing to give back — while training still stows, because training is you doing it. It had been crowding out the thing you wanted anyway: the bat sweeps a husk away ten times a second and six of them filled the bag within a second. And a hole’s name is legible now: half again as wide, a third as deep rather than a quarter — but not so wide that two of them touch and read as one long plate.

The “ball” in pong world still slows down after a minute or so

Right, and I had measured the wrong game: pong and pong-classic are two different programs and Ken plays the first, which copies and sends two message boxes a round — about two hundred and forty fresh numbers a second at Instant. Every number the workshop makes goes on allNumbers, swept twice a second to decide which are close enough to draw with more digits, and the sweep dropped a number WITH NO PARENT. But a number inside a message box is parented to the box, and a thrown-away box takes its numbers with it still attached. Measured after 300 frames: 1230 on the list, 19 parentless, 1200 parented to something no longer in the world — fourteen thousand entries a minute, each given a position and a distance twice a second. Frame cost 9.5 to 13.8 to 57.5 ms with the scene flat at 1402 objects: arithmetic, not graphics. disposeThing already means gone for good; now it marks what it touches and the sweeps drop anything marked — nests on the mark ALONE, since a nest in Dusty’s bag has no parent and must still receive mail. Third time for this shape: removed from the scene is not removed from the program. So it is a test now — the sweep moved into advanceLOD, which the harness calls too, and the suite switches on both of Pong’s players and fails if the list passes 800. Proved by putting the bug back: 682, 1169, 1646, 2133, 2608 and a red FAIL. Its FIRST version picked the players by bench index, switched on a number called misses, watched a dead world hold at 195 five times and said PASS — a gate that passes because nothing happened is the bug it exists to catch, so it finds them by what they are and checks the ball moved. The syntax gate moved out of a scratchpad into tests/ for the same reason.

I put the square ball from pong.world on Mimi and it got stuck

tiny-robot corrected entering run: 0.24 1

It did, and the console said so six hundred times: “no place to move”. The ball is a gadget — a pad carrying a panel of robots and a speed — and switched on, its panel takes a turn every frame. Set it on Mimi’s platform and the panel goes on taking turns, but the ball is at a station now, so thingPlace gives it nothing and every round its robot tried to move it, failed, and said the failure out loud. It sat there being told to put itself on the table for as long as it was left there. The missing rule is one the table already implies: A THING THAT IS NOT ON THE TABLE IS OUT OF PLAY — in your hand, in a claw, in a hole, in a house, on Mimi’s platform, it is not in the game, so its behaviour waits. It stays switched ON; it has nothing to act on until it is put back, and then it carries on from where it was. That is what a robot facing a bare nest already does: not stopped, waiting. One line, and cheaper than what it replaces — a panel that can do nothing is skipped before its turn rather than after it has failed. After: six hundred ticks on the platform, zero complaints, still switched on, the copy comes out of the tray, and back on the table it is moving again inside three seconds; classic Pong, whose ball rides a field, untouched. The sentence also named the wrong machine — every station was “on the robot’s own desk”, true of the stand and quite wrong for the copier. The tiny-robot line was not the bug: a once-per-robot diagnostic with a captured stack, not a throw, and a Pong world has a dozen panel robots drawn at a twelfth scale. It is a test now — silent, still, still switched on, moving again — proved by putting the bug back. Its first draft asked whether the ball had moved by comparing finish against start, and THE BALL BOUNCES: on the artifact run it finished where it began and went red on a world running perfectly well. Position is periodic; it samples every eighth frame now and asks for the spread.

I was able to copy a ball from pong.world that had never been turned on but when I clicked pause to stop the bouncing ball and placed it on Mimi the copying stopped.

When I copied the ball that had never run and placed both on the table and started them they ran ok for a while but then one disappeared.

The pause one was the plainest kind: tick() is the only thing that drains the step queue and the pause gate sat in front of it, so while paused NOTHING the user did could finish — not a copy, not putting a thing down. Nine hundred frames with the ball on Mimi’s platform, the queue climbing to five and never moving. Wrong cut, and Ken’s own use of it shows where the cut belongs: he paused the ball PRECISELY SO THAT he could pick it up and copy it. So a pause stops the WORLD running itself — fresh turns, speeds, touches, eggs, birds — and leaves the WORKSHOP alone: the queue drains whenever the floor is yours, and a robot caught mid-round holds its breath where it stands. The guard moved inside processDirtyRooms rather than its call sites, because afterQueue calls it too and that back door would have let a panel start a round the moment a copy came out of the tray. The copy one was half solved: copying rewrote the copy’s event guid as a whole string, but a thing has SEVERAL channels and a channel wears the guid with the channel after a hash — evt-P901#edge — a different string, never touched. The copy’s panel mentioned the original’s id twenty times and its own fourteen, so both programs read one ball’s senses; they ran ok for a while because for a while the two agree. Both forms are replaced now, each closed by a character that cannot appear in a guid, so neither runs past the end of one id into a longer one — the first time an L9 meets an L90. The copy is a real ball now. The OTHER half is not fixed and is written up as open: after being copied the ORIGINAL stands still, and the copy’s existence is irrelevant — vacuum it immediately and the original is still dead. Its identity survives, its nests survive, its panel is on and taking turns, and its move fails with “no place to move”. That points at ctxToRec’s pushWorld/worldOut/popWorld round trip over the running panel. Also recorded: two of my own probes picked the ball by bench position, which changes when a thing is picked up, so they watched the bat instead — select by lid.

I don’t understand [the two-forms explanation]. I thought that copying produced an identical structure with fresh nests and birds (and their guids). I also thought that serializing and recreating would act like that. So I put the classic pong game in a notebook and took a copy twice. One copy ran briefly and then the ball got stuck in the corner.

I held the classic pong game and it ignored the − button to shrink it.

Ken’s model is the right one and it was NOT implemented — hand-rolled at Mimi, absent everywhere else. The notebook path built copies straight from the stored record, and thingIn registers anything wearing a lid under that lid — so every copy wore the record’s identity and each new copy EVICTED the one before. Things are addressed by name; the dispossessed ball still glides but its robot’s bounce messages land on whoever owns the name, so into the corner and stuck: the screenshot. And Mimi’s hand-rolled rename had been wrong twice in two rounds — the #channel guids, then riders referencing SIBLINGS. Hand-rolling per door is the bug. One mechanism now: rekeyRec finds every identity a record DEFINES, mints fresh names, re-addresses birds, bindings and event guids — and leaves alone what it merely references, because a copied nest joining the original’s flock is ToonTalk’s own rule. Applied at the notebook, at Mimi, at a robot’s thought; a live pad or scene copies as thingOut, rekey, buildFromRec — the serialize-and-recreate Ken assumed. Its first version renamed IN PLACE, and thingOut does not clone a closed panel — r.panel IS the live thing’s panelWorld — so copying a closed-panel ball rewrote the ORIGINAL’s program and its robot went deaf after one round; the interactive test missed it because that tray happened to be open. rekeyRec works on its own deep copy now, and that also settles last round’s “original goes still” — half broken harness, half this mutation. The minus button: setPadSize clamped at a floor of 1, so a six-tablet pitch could never shrink; a quarter now. Check seventeen, “copies are wholly their own”, in two halves — the copy’s record shares no DEFINED name with the original’s, and ball, copy and copy-of-copy all sweep the table. With the renaming disabled: 0.0/0.0/3.2, Ken’s report in numbers. Its drafts failed three times — home read while the thing sat on Mimi, “the ball” selected as the first gadget (the bat), three full pitches on a bench that cannot hold them — and blamed the app each time. A harness is code too.

Resizing Pong should resize its parts as well. / Let’s enable Marty to provide a high-level description of what a robot or an anima-gadget does. / The run/pause button should only apply to all robots everywhere — not tools and birds. / Is it time to finish the library of anima-gadgets? / I expected that if I dropped an anima-gadget on the panel of a picture it would obtain those behaviors. / Maybe resources should always be put into a notebook and not in world files. / If Dusty vacuums something that is running it should be turned off. / It seems you should have been able to catch some of the recent bugs without my testing.

Six built, one owed, one confession. Riders scale with their field — the 0.75 cap was absolute, so a shrunken pitch carried full-sized players; it scales with sz now and a half-size game still plays. Pause is the robots holding still: movers hold, birds finish their deliveries, eggs hatch, Mimi copies, and a robot woken by a paused-time delivery waits for Run. Dusty switches off what he takes — directly, not through switchGadget, which would conjure a tray — and a returning speed re-joins the movers; a tray stranded off the bench comes back with its thing, because SPACE was lighting a panel no list held. A behaviour dropped on a thing’s PANEL binds to the thing — the old rule matched the tray first and bound the behaviour to a room that is nothing; drops on rooms never pass through combine, so the rule lives at the door they actually use, and binding a ball to a plain pad makes THE PAD bounce. A world imported mid-project lands as a notebook of its things, nothing wiped, fresh names per page. Marty gets the FACTS of every behaviour in reach and a rule: answer WHAT with the purpose of the loop, steps only when asked HOW — the first cap dropped the 2800-character team brief whole and the facts block was always empty. And the confession Ken’s challenge earned: dustySuck began if (!dusty) return, demo frames build no mascot, so in the SUITE’S frame every robot vacuum has been a silent no-op all along and the goldens faithfully recorded the wrong machine — n-to-1’s golden ended with the stand occupied and a nest of empty boxes, a program that never worked in the frame that certified it. The fallback stows without the mascot, queued so a vacuum keeps its place among the round’s steps; six goldens moved for the better, n-to-1 now ending in the finished 5-4-3-2-1 chain. A missing model must never mean missing semantics, and a golden is only as honest as the frame that made it.

Let’s finish the library of anima-gadgets while I do some testing

The shelf is twelve. The blocked six wanted what the plan said: a sayable SIZE and arithmetic against the touch channel. Both went in as small message-surface additions — size joins across, away, position, speed and solid, in the units the card’s + and − buttons step, and [set | speed] announces on the #speed channel with the numbers’ echo rule. Two idioms carried the gadgets. DOZING ON TOUCH: the touch nest starts empty, the team dozes till an announcement lands, eats what it acted on — grow grows once per change of contact and an untouched gadget costs nothing. THE SCALE IS THE IF: the speed limit weighs the across-speed against the limit on an ordinary scale and the lean dispatches — born at 0.9 with a limit of 1/2, SPACE alone shows it braking, 0.9 to 0.5 in sixteen frames. The bell and the score ride in their gadgets’ work boxes, because a live thing on a folded tray’s bench hydrates unparented and cannot get its mail. Reverse-on-collision handles things and leaves edges to bouncing — bind both to one star and it is a pong ball with no training anywhere, the composition the shelf exists to teach. And the harness lied twice more: at Instant the mover TELEPORTS across the grow pad between touch sweeps (contact happens in sampled time; the check walks now), and — structural — every check stamped frames with performance.now()+i*17, a clock seconds ahead of real time, while the touch sweep’s dedup timestamp is global: one check’s synthetic future convinced the next check’s sweep that no time had passed, and my manual repros “worked” only because real seconds passed between tool calls. One monotonic virtual clock for the whole suite now. Check nineteen: all twelve present, the limit caps itself, grow grows under a drive-by — and with size removed from the surface it goes red.

When I shrank the classic pong game the paddle stopped moving though once it moved and stopped. / I couldn’t drop an anima-gadget nor its panel on the panel of an image. / I tested Marty with a pad with an anima-gadget on top. It didn’t seem to know much about what I was holding.

The paddle: a rider’s place was computed in DISPLAY units — at.u times a width that includes the field’s chosen size — so the bat’s program, authored against the full pitch, aimed outside the shrunken one and pinned at the clamp after one move, which is exactly what “moved once and stopped” looks like. The missing rule: a rider’s place is said in the field’s OWN units, however big it is drawn — shrinking changes how a game looks, never what its numbers mean. Display size divided out of thingPlace, the clamps and the write-back; at natural size the division is by one and the goldens hold; the half-size classic plays measured, ball sweeping 0.79, bat following at 0.53, now a suite leg. The bind: it listened at roomDrop and combine — the routes a synthetic clickThing takes — but a real drop lands on whatever PART of the tray the pointer hits, work box, perch, plaque, wall, each with its own click meaning handled before the general routes; dropping on the perch GAVE the gadget to the picture as a message, which swallowed it. One intercept at the head of handleClick now: a held behaviour, or its open panel, dropped on any part of another thing’s panel binds to that thing — proved on an image’s panel via the perch, and the picture itself marches. The harness lesson again: named-target clicks take the polite route; a mouse hits what it hits, so features must be tested through the hostile pick kinds. And Marty: the facts never said WHERE a behaviour stood and the hand line said “a blank pad” full stop — the hand names its riders now and every behaviour’s facts say where it rides, so “what am I holding” has something to hold on to.

I’m away for a few hours — can you come up with new tests and run them

Nine probes, aimed where the bugs have actually come from: combinations, save/load round-trips, and published claims never proved. Eight held, by measurement: the composition claim is TRUE (bouncing + reversing bound to one star wandered 3.06 across and turned 43 times — pong-ball physics, no training anywhere); bindings survive a save/load; a shrunken game survives a save/load and still plays; vacuuming the TARGET of a working behaviour is graceful and the drive resumes when it returns; a Mimi copy of a bound gadget stays bound to the same star and both drive it at double pace; shrinking mid-play does not interrupt; the half-size game plays straight-on and Escape restores; a filed binding survives the notebook page. Probe eight found the bug: binding the speed limit to the classic BALL — limit the ball, a legitimate wish — fell through to the pad-join rule and MERGED THEIR FACES, because the guard read not-a-gadget: a behaviour could bind to anything except another behaviour, and the ball is one. Joining two gadget pads is never what anyone means — it silently discards the dropped panel. The guard is target-is-not-itself now; middle still rides, edge binds, and the limiter attached to a running game plays. Harness notes: three probes were eaten by clickBench parking drops into nearby pads’ ride/join semantics, one renaming a shelf gadget to “shrink when touched**” — the harness has place(t,x,z) now, the tripod, while clickBench stays the way to test what a user’s drop would do. Twenty checks: BINDINGS TRAVEL, proved to bite by putting the old guard back. And probe ten found a second bug in a sentence the manual had promised for two rounds — “wake Ruby and click it and it works on itself again”: the release branch sat BELOW Ruby’s erase-in-place, which catches every thing-click first — dead code, and a Ruby click on a bound behaviour quietly ERASED it. Release comes first now, scoped to bound gadgets, measured working. Both of the day’s real bugs were found by reading published sentences back to the app.

I guess we’ll go with speed being built-in. But should it be x-speed, y-speed, and z-speed? And as an exercise it would be interesting to see if we can build it from the current functionality in principle. / Yes let’s introduce inexact numbers as discussed / I thought we got rid of world bottling. If not what is holding us back?

Stage 6 shipped: a number is a rational plus an exactness flag, with three operations inexact by nature — sin, cos, root — typed onto a held number as mod always was, and ignoring the number they are written on: the badge is the whole message. Degrees, because a child drawing a circle knows 360. NOTHING CALLS JS Math: Math.sin is implementation-approximated by the spec, so two browsers may differ in the last bits and a saved world would replay differently elsewhere — instead argument reduction and a Taylor series over rationals, Newton over BigInts for roots, twelve places kept and thirty worked. sin 30 is exactly 1/2 and MARKED; the square root of 4 is 2 and stays EXACT, because a root that comes out whole is not an approximation. Exactness is part of equality, so a thing told it is now approximately a half has genuinely changed. The marker is a wavy equals and a decimal, never a fraction. The ellipse is the thirteenth behaviour and stays off the capped shelf — four badged numbers on a running total, twice, plus a step; 2.2 across by 0.8 deep, every point on the curve. On SPEED: it can be built from what exists — “moving right” on the shelf IS speed made of robots — so the question is what the primitive buys, and measured it is exactly one thing: a robot’s move is distance per TURN (60 rounds 2.000, 30 rounds 1.000) while built-in speed is distance per SECOND (0.900 at 60, 30 and 15 fps). A game that runs differently on a slow laptop is one a child cannot debug. On x/y/z: the workshop is a TABLE — place, edges, touching and fields are all two numbers — so a third axis is not a third number on speed but a three-dimensional world, an epic not a tweak; and the per-axis question is already answered by the empty-hole idiom the speed limit is built on. And BOTTLING IS GONE — the memory note saying otherwise was stale. A room hydrates once and entering it swaps a bank of globals; there is no serialisation in the running path. Measured against a 29-fold bigger outer world, the run alone is flat at two to four MICROseconds; what grows is the per-frame scan for dirty rooms, which any design pays. What is left of the engine/view split is one execution context (which blocks multi-threaded houses) and every world being real 3D whether watched or not.

Can you implement a turtle that responds to forward and right messages

Built as a BEHAVIOUR, not a primitive — the shelf’s own card says there is no move and no bounce, only messages a thing already answers, and a turtle is that claim under more pressure. Forward is across + n x sin(heading) and away + n x cos(heading); right adds to the heading. Every line is badged numbers dropped on a running total: a copy of the heading, the sin badge, then the distance taken out of the order and TOLD TO MULTIPLY. It hears through a NEST in its work box — a letterbox — whose top the two robots read, dispatching on the word, the same shape as the arrow-key gadget on key names and Pong’s ball on edges. It needed Stage 6: after [right 30] a [forward 3/10] moves across 0.1500 and away 0.2598, a step of exactly 0.3000 along a 30-degree heading — before inexact numbers a turtle could only have turned in quarters. Then the turtle made an old promise measurable. Ken had asked rounds ago whether a dozing robot registers with what it waits on, since in ToonTalk there is no penalty for a huge number of them; it did not, and one turtle asleep on an empty letterbox cost 0.08 ms EVERY FRAME. The reason: THE POLL WAS THE WAKE — taking the turn is what noticed the mail, so skipping it would have meant never waking. The wake got its own signal instead: nestReceived already walks up to the containing panel, so it leaves a mark there, and the scheduler steps over a sleeper whose mark is clear. One sleeper: 0.0795 to 0.0240 ms/frame, 1400 turns to 47; thirty sleepers 0.30 instead of a projected 2.4. A delivery still wakes it on FRAME ZERO. Not yet the full registration index — the scheduler still walks the list, so it is linear with a tiny constant rather than flat. And the change broke “a thing off the table is out of play” within a minute, for a reason worth keeping: THERE ARE TWO SCHEDULERS, and the out-of-play rule lived only in the first — harmless while that one always had work, fatal once sleepers stopped filling it. Both tests are shared functions now. A rule that decides whether something runs must be asked by every path that can run it.

“Her nest is gone” when I tried the turtle world. Also the arrangement wasn’t so good — the bird behind the messages and the messages crowded. How can we add “pendown” and “penup” to the turtle? / For the ellipse it worked but the anima-gadget couldn’t be added to the picture or its panel

Her nest was ASLEEP, not gone: the letterbox is authored inside the turtle’s panel, a panel does not exist until hydrated, and a gadget nobody has switched on is exactly where a FIRST order arrives. The delivery now looks for a closed panel whose record holds a nest wearing the guid, wakes it folded, and asks again — and since deliveries mark panels dirty, a posted order also STARTS the turtle, which is what mail is for and what houses have always done. Measured: an order posted to a never-switched-on turtle steps it 0.3. The pen went in as a THING PROPERTY, not a turtle feature: [set | pen | down] makes any thing draw as it moves — each placeThing leaves a chalk stroke, on the table or scaled onto its field — up lifts, clear rubs out, query answers. Chalk, not things: unpickable, unsaved, capped at six hundred so an afternoon of turtling cannot fill the machine. The turtle then learns pendown and penup as two more members dispatching on bare words — eight lines of authoring. The full ritual measured: pendown, forward/right-90 four times — the path CLOSES to 0.0000, exactly four strokes; penup, forward — still four. The world rearranged: bird in front, orders in one spaced row, the TRY card teaches the pen. The ellipse-on-picture report could NOT be reproduced — bound and traced clean through every headless route, one earlier “failure” being the session’s own contaminated page — so Ken is asked what the workshop SAID at the refusal: the say line is the fingerprint.

Time to do: rebuild Pong out of library gadgets — see how close it gets. A place for Marty’s abstractions to earn their keep, and your judgment on his answer quality. The dozing-robot registration index — the bank-account world is the canary.

Pong from the shelf plays: the ball is a pad with three shelf gadgets bound to it, the bat a pad with one, no robot written for the occasion — roams 3.2 by 1.1 bouncing both axes, rally climbing under a perfect pointer-player. The rebuild taught four things in the order they were met. Bouncing was ONE-AXIS and a free ball pinned at the near wall — it grew an away step and two members, since a thing called bouncing should bounce off every edge. A blind replace of G912 ate the front of G912S — the longer-id collision rekeyRec’s comment warns about, met in authoring — and 470 scored contacts went to a tally wearing a mangled name; the “fix” then renamed the whole inner tally to the bench score’s id and two things claimed one name, the copies-clash re-created by hand. Rename the suffixed id first; re-aim BIRDS, not identities. Step-movers compose by ADDITION — playable, and a seam that argues for built-in speed again. And the rally scores HITS where classic Pong scores misses — the seams are on a card IN the world. The registration index went in: a dozing robot writes down the guids of the bare nests that blocked it, and a delivery asks only the robots registered on the nest it just fed. Proved with an army: thirty turtles dozing, one order posted to number seventeen, exactly [17] moved. The bank-account canary’s golden did not move. Marty’s showcase is pong-gadgets itself — a purpose written on no single panel — with an ASK MARTY card; two facts gaps fixed (labelled pads and numbers were nameless in his brief); the abstraction half of the judgment needs Ken’s machine, since this environment has no brain.

Why did the save password appear soon after I switched from Claude API to ChatGPT? Marty did well (both Claude and GPT API). But the gadget pong game doesn’t run — space has no effect on the ball, the anima-gadgets do nothing too. The paddle is hard to find since the score and notebook are in the way.

Three fixes and a verdict. SPACE on the ball did nothing because the ball is not a gadget — the gadgets are BOUND to it, and SPACE only knew gadgets and scenes. A thing with behaviours bound to it now switches as one by SPACE and “.” on the thing itself: switchBound, used by the key handler and by the suite, whose pong check drives through it. The gadgets “did nothing” for the deeper reason the screenshot shows: the red notebook means the world arrived mid-project as a NOTEBOOK, and page-takes rekey their copies — so boundTo still named the record’s V901 while the taken ball was a fresh L-something. Cross-page bindings are cut by design; the fix is honesty at the moment of failure — switching on a behaviour whose bound thing is not here now says so and says what to do, with the aliveness test deliveries use, because liveReg can hold a stale entry and mere existence was defeated by exactly that in testing. The password prompt was the API-key field: a real type=password input, so Chrome offered to SAVE the OpenAI key — the key never left localStorage, but the field is a CSS-masked text input now and Chrome has nothing to offer about it. The bat stands in the clear front-right, the rally front-left, and the RUN card teaches the new SPACE. And Marty DID WELL on both the Claude and the OpenAI keys — Ken’s words — closing the judgment the last round could only half-deliver.

The square root of 2 worked but the English didn’t make sense. Note how the tooltip is in the way of reading it. I couldn’t rotate the cube with the arrow keys but then later I could. Inexact numbers should look different. The English should note that it is inexact, and the tooltip doesn’t need the approximate fraction equivalent — it should say it is inexact.

Five reports on the inexact rollout, five fixes. The words face fed the raw rational to the English speller, so √2 read “one trillion four hundred fourteen billion … over one trillion” — the bookkeeping denominator, in words. An approximation is READ ALOUD now, the way a person says a decimal: “about one point four one four two…”, and the suite asserts the spoken form. It looks different at a glance: a BROKEN frame on every face — a number that is not exact is not dressed in an unbroken line — and the underside gave up its continued fraction for owning up: not exact, only the first twelve decimal places are kept. The tooltip said too much and too little: it offered the mixed-form trillion-part fraction (false precision from the improper-fraction courtesy, now guarded) and never said inexact (now “an approximate number, not exact”). The tip also sat ON the face being read — worst while carrying, when the thing is at the pointer by definition — so it goes under the thing’s projected screen box now, above when there is no room, docked at the bottom failing both. And the intermittent arrow keys were the Speed select keeping the keyboard after a mouse change — the click on the world that took it back is why “later I could” — cured like the clicked-button rule: a deferred blur on change, for every select.

Why didn’t you catch this during your testing? The ball moves but it slows down as it passes through text pads and its bounces are sometimes not very natural. The anima-gadgets still don’t behave on their own. And you were wrong about it loading as a notebook — that wasn’t the case. The paddle follows the cursor everywhere; it should only follow vertical motion. I couldn’t turn the paddle off.

The honest answer first: every check drove behaviours with switchGadget() — the inside function — so twenty-three checks proved the simulation and not one ever pressed a key. There is now D.press(thing, key): a real pointermove and a real keydown, which the pong check goes through. Four bugs behind the rest. OFF IS A DECISION: nestReceived marked every enclosing room dirty so post could wake a sleeper, and could not tell idle from switched off — the pointer posts sixty times a second, so the bat came back to life inside a frame of being stopped, for ever. A stopped panel says so now and post leaves it alone. THE BALL SCORED AGAINST THE DOCUMENTATION: the cards, the counter and the gadget cards were solid, so with the bat lifted off the table the rally still climbed to 69 in 700 frames, 39 of them while the ball sat on a doc card — and each contact ran a scoring cycle, which is the stall. They are scenery now: 150 frames on a card, rally 0. THE BOUNCES: step-based movers run a robot cycle every round, and a cycle builds boxes and flies birds — 26ms a frame for three gadgets against 0.2 idle, so the ball moved as unevenly as the frames arrived, which the harness could not see because it feeds fixed 17ms steps. Two new shelf gadgets move on the world’s clock instead — bouncing at a speed, and reverse a speed on collision, which fills ONE hole of the speed box and leaves the other empty so the two never argue — and Pong is rebuilt on them: 0.2ms a frame, two distinct step sizes where there were dozens. AND THE BAT IS A WALL AGAIN: following up and down, classic Pong’s own bat robot promoted to the shelf, which is also what makes it pointable enough to stop. Fifteen on the shelf, twenty-five checks. Not reproduced: a gadget card refusing to start from a clean load.

I couldn’t turn off the ball — it ignored “.” while moving and definitely when I held it. I accidentally dropped it on a text pad and then undo returned a blank pad. When all robots are paused it is easy to forget — maybe different lighting? I dropped a PNG on the desk and all I see is “(a picture on the way)”. When I drop an anima-gadget on a pad’s panel the behaviour is updated but the gadget ends up on the desk. Testing the library became very slow.

Six reports, and the first is a regression one round old: rebuilding Pong on the world’s clock made the ball a plain pad carrying a SPEED, and advanceMovers only ever gated gadgets — so “.” quieted all three panels and the ball glided 0.649 further anyway. Stopping now parks the speed and starting puts it back; drift after “.” is 0.0000. “Undo returned a blank pad” was the visible corner of something much larger: undo returned a world with no colours, no names and nothing bound to anything, because snapshots are taken with the MATCHING spec, which describes a thing as one of its kind — correctly, since a robot expecting “a pad” must not start expecting a yellow one called the ball. A full spec now carries look, label, bindings and shape, and only the snapshot asks for one. Found while fixing it: a pad’s label was never SAVED at all — every other kind wrote one — so a saved world came back nameless, which also blinds Marty. And the ball had not so much been dropped on a card as EATEN by it: pads join at the edges, its own words were empty, so it vanished without changing the card by a letter and took three bindings with it. A named or bound pad refuses that now, and says where to drop it instead. The pause got Ken’s own remedy: the light goes cold and low and the ground goes blue, since nothing is moving to notice the absence of. The stuck picture could not be reproduced at 3.9MB, so it is guarded by construction — oversized images are redrawn smaller before storing, and the load is raced against a clock so silence is impossible. The bound card lands beside its panel now, with the reason said out loud. The library slowness is measured and is not a leak: one step-based gadget costs 17-23ms a frame against 0.1 for a speed-based one.

What does it mean to be “touched”? If it means clicked, that picks it up; if it means another object collides with it then touched isn’t the right word. I don’t understand why the library is slow — why should one step-based gadget cost 17-23ms a frame? I’ve attached the PNG that still shows as loading. And the tooltip says I can drop the panel on the other panel, but it isn’t added to the panel — it shows up next to it.

The performance challenge was the right one to make, and it needed a profiler rather than a shrug. Per phase, one step-based gadget: tick 8.0ms, panel work 7.5ms (partly a deliberate 8ms budget), everything else 0.4. One level down: the simplest gadget runs 0.903 rounds a frame at 8.23ms a round, and building the pieces of one message box costs 2.76ms predicted and measured — of which the two TEXT PADS are 1.04ms each, because a pad’s face is a 512x384 canvas and fitting the words is a SEARCH: wrap, measure, shrink, wrap again. Every one of those faces was painted inside a FOLDED panel, for a copy a bird carries off and the round destroys. So painting waits now: a pad built where nothing can see it records its words and paints nothing, and a bounded list catches up the moment anything could look. A round is 3.95ms, the frame 7.43 to 3.57, one bouncing 15.9 to 8.6, the whole shelf of fifteen 24.5 — from a state where the same measurement timed out — with identical rounds per frame, so the work is the same and only the waste is gone. TOUCHED was indeed the wrong word, and the shelf was inconsistent with itself: the cards say grow and shrink when BUMPED now, the channel keeps its stored name so saved worlds still open, and bump/bumped/hit are accepted as one word. The panel tooltip promised what the code would not do — a behaviour binds and waits beside, since one filed inside a panel never gets a turn — so it says that now. The picture still cannot be reproduced: a screenshot-shaped PNG lands here in under a second, so the pad now records what it is waiting for and says the size when it gives up.

What is taking so much time if the robots are not seen? Panels should be able to nest to convey different purposes (movement vs sounds) — it affects the implementation but matters conceptually, and makes macro anima-gadgets easier to alter; when not seen they can be a flat list if that is better. And I can drop an image with the latest version.

The remaining milliseconds, measured by patching the browser’s own APIs rather than guessed: per round the simplest gadget allocates 15.5 canvases costing 0.074ms, calls measureText 10.3 times costing 0.148, touches the interface for 0.012 — six per cent between them. The other 3.7ms is the workshop being literal: a round BUILDS a message box out of real meshes, materials and textures, about twenty objects, hands it to a bird, delivers it and throws it away. Cross-checked: bouncing, with five robots and two messages a round, costs 3.07ms against moving right’s 3.5 with one robot and one message — the cost tracks messages built, not robots matched, which is the signature of construction being the cost. The next win is the same trick one level down: make the canvas itself lazy, not just the painting. On nesting, both of Ken’s suggestions were right and half of it now works: SPACE on a macro sets every behaviour grouped inside it going and “.” rests them all, a panel whose work IS its parts is no longer refused, and the scheduler reaches nested panels through exactly the flat list he proposed — necessary because a nested tray sits on no bench the scheduler walks, the bench it belongs to being a snapshot that exists only while that world is current. What does not work yet, stated plainly: a part inside a panel cannot move a thing, because a place is resolved against the current world and a nested part’s world is not it. Nesting groups today; it does not yet drive.

You are right that a nested panel on a panel does not drive its object but the object of the top-level panel it is a part of. If it is removed and its object is restored then it can run independently. The lazy allocation sounds good — do it.

The sentence about semantics dissolved the blocker I had reported. I had been looking for a way to let a nested part move a thing inside its own panel; it should not be driving that thing at all — it drives the object of the panel it is PART OF, reached by an ordinary bird exactly as a top-level behaviour reaches a thing on the table. With that, one guard was left, and it was asking about the wrong subject: OUT OF PLAY exists so a behaviour whose thing is off the table does not spin uselessly, but it asked about the CARD — and a part nested in a macro’s panel is on no table of its own, so it was silently denied every turn: dirty, registered, never run. It asks about the thing the behaviour DRIVES now. Measured: the outer star moves 2.73 across the table driven by a part living inside a macro’s panel, and “.” on the macro rests it. Twenty-nine checks. And the lazy allocation: deferring the paint had left the allocation behind, so a pad built out of sight still made a 512x384 canvas and a texture it might never use. The canvas is made the first time something is drawn on it, and unpainted pads share one 1x1 texture. Canvases per round fell 15.5 to 11, and a round to a warm median of 2.78ms. The whole journey: 8.23ms a round, then 3.9 once faces stopped being painted out of sight, then 2.78 once they stopped being allocated — with identical rounds per frame throughout, so only waste was removed.

The screenshot shows the result of dropping the same file on the desk 5 times — it worked fine 3 times.

The same file three times right and twice wrong is not a file problem, and it was not a decode problem: the picture had loaded every time and the canvas held it perfectly. What the screen showed was an upload made before it. A pad takes the PICTURE’S proportions the moment one loads, which resizes its face canvas — measured on a real drop, 512x392 becomes 512x398 — and a resized canvas needs a fresh GL texture, as the number faces have said in a comment for ages: updating in place trips glCopySubTextureCHROMIUM against the old allocation. The pad never did it, so the canvas was repainted with the picture while the GPU went on showing the words “(a picture, on its way)” over a picture sitting right there. The pad renews its texture on resize now, and check thirty asserts all three parts: the canvas is resized, the texture is a new one, and the face carries the picture. The lesson is sharper than the bug: for three rounds I checked __imgEl and userData.img and pronounced the path healthy. Those are the app’s opinion of itself. What mattered sat between the canvas and the eye, where nothing I had written could see — and a test that cannot see what the user sees is not testing what the user reported.

I tried to drop a panel on a panel but they just end up nearby. Marty didn’t seem to know that in my hand was an imported image with 2 gadget panels associated. I gave the sound’s bird the 3-hole box and the sound didn’t make a sound. I think notebooks should have page numbers. When I grab a copy from a notebook page it doesn’t animate as if it came from the page. Pendown didn’t seem to have an effect on the turtle. I think fd 100 should move the distance that 1 does now. The state box of the turtle should have box text describing what is in each hole.

The drop finally does what the tooltip promised: a behaviour dropped on a panel goes INSIDE it, since the reason it was kept out — a panel filed inside another never gets a turn — stopped being true when panels learned to nest. It binds to what that panel’s thing is bound to, and taking it out releases it. That raised a new question: with the card off the table, what does a person press? The thing itself — SPACE on any thing now starts what is grouped inside its panel as well as what is bound from outside. Measured: drop moving-right on the star’s panel, press SPACE on the STAR, and the star crosses the table. A sound now answers the box that makes one however it arrives — the parser is shared between hand and bird, so 440/half/sine delivered by bird sings; before, a sound knew only play and stop and the box was swallowed. The turtle speaks Logo’s units: the scale went into the BOX rather than the robots — hole 9, step size, one hundredth — so forward 30 moves what forward 3/10 moved, forward 100 is a stride, and a child changes gait by changing one number in plain sight. All ten holes carry their names. The pen was never broken; at the old scale an fd 100 flung the turtle into the wall, which is what “pendown has no effect” looked like. Two test lessons: the longer order overran the check’s frame budget, and raising it did not help, because the real cause was a rename I had missed on the BACKWARD order — the check was handing the turtle nothing, which looks exactly like a turtle doing nothing. Also: notebooks have page numbers, a copy lifts off the page it came from, and Marty now names a picture as a picture and lists the behaviours attached to a thing.

When I put the turtle’s panel on a picture’s panel it still doesn’t become part of it visually, and folding the panel leaves the turtle’s panel behind. “right” messages should also rotate the pad. When you say that “pendown” works why don’t I see a trail? Even closeup it is hard to read the box labels, and the nest covers one. The turtle image is nice but the background should be transparent. There should be a “door” on panels in order to watch the robots run.

There was no trail to see: every stroke was laid five millimetres above the FLOOR, while the turtle drawing them stood at 0.865 on the table — the chalk was under the furniture, hidden by the table top from every angle. A bench thing carries the table’s height in its own y and the stroke code used a bare constant. It takes the drawing thing’s own height now: strokes land at 0.846, table top 0.842, turtle 0.865. And the suite said PASS throughout, because its pen test COUNTED meshes of the chalk colour — the third time in a week the same mistake has cost Ken a report: the picture that had loaded, the behaviours that were registered, the strokes that existed. Existence is what the program believes; position is what a person sees. The check now measures each stroke’s height against the turtle’s, so a trail on the floor fails. Also: hole labels at twice the pixels in darker ink and set further out in front, because what stands in a hole leans over the plate and a nest was sitting on the word “orders”; and a pad can now have NO PAPER — [set | background | none] clears the face and makes the slab’s sides invisible, which the turtle’s shell now uses, so it is a turtle rather than a turtle on a tile. Not done and owed: rotating the pad on “right”, the panel left behind when its owner joins another, and a door to step into a panel and watch.

right rotates the pad. I think we need the convention that a heading of 0 points to far edge of the table or the far edge of the containing pad.

The convention was already half-present and never said out loud: a step forward has always been across = SIN(heading), away = COS(heading), which IS “zero points at the far edge, degrees clockwise”. What was missing was turning the thing as well as counting. facing joins the message surface — [set | facing | 90], [move | facing | 30], [query | facing | bird], with heading and turn as the same word — stored on the thing, so it saves, reloads and survives an undo like anything else a thing is. The second half of Ken’s convention cost nothing: a child’s rotation is measured in its parent’s, so a thing riding on a pad turns relative to THAT pad’s far edge without a line of code for the case. The turtle’s right now does two things where it did one: adds to the heading, then fills a [set | facing | _] from that same number and hands it over. Measured: right 90 turns the pad a quarter turn and the next forward 30 moves 0.3 across and nothing away — it walks where it points, which the check asserts as a pair, because a turtle that points one way and walks another would be a lie told in pictures.

The pen trail should be a first-class object — even when it is part of a pad it can be vacuumed off, so a turtle can create 2D (and later 3D) sculptures. We should add pen color and pen width too. The screenshot is fd, rt 30, fd but it looks like it did a right 90 instead. Also: importing a world as a notebook breaks connections between objects — maybe the contents should be in one long box. And when I give the bird a message to a picture that has the turtle panel, the bird doesn’t fly to where the picture is even though the message is delivered fine.

The right angle was the pad running out, not the turn. On the table: leg one bears 0, leg two bears 30, the turn is exactly 30. On a pad — Ken’s screenshot — leg two bears 90 with the legs different lengths, 0.242 and 0.15. The pad is 0.68 deep and the stride is 0.3, so leg one spent the depth and leg two’s AWAY component was clamped flat at the edge, leaving only its across part: a right angle drawn by arithmetic that never happened. The remedy is already in the world and is why step size was put in the box — a turtle drawing on a pad wants a smaller stride, one number — but the honesty is still owed: a move flattened by an edge should say so rather than leave a drawing that lies about the angle it was given. The pen now has a colour and a width: [set | pen | red], [set | pen | 3], both kept on the thing that draws and on each stroke as drawn, so a line can change colour halfway (and a new colour breaks the line so the joint is not drawn in the wrong one). Chalk comes off — a stroke answers Dusty and the one he is pointed at is the one that goes — which is the half of “first-class” Ken named; a stroke you can pick up and file wants a record of its own and a place in the saved world. Found while testing by round-tripping a world: whether the pen was DOWN was never saved. Not yet done: the notebook-import proposal, and the bird that delivers correctly but flies to the wrong place.

the box next

A world imported mid-project now arrives WHOLE: page one of its notebook is the entire world in one long box with every hole named, and the pieces keep their own pages after it. Ken’s diagnosis was exactly right, and the cause is the rule that makes copies safe — a page hands out a copy, every copy is rekeyed so it cannot steal the original’s mail, and taking things one page at a time renames each SEPARATELY, so a behaviour from one page goes on naming a ball only another page knows: a binding surviving as a name pointing at nothing. That is what bit him in round 34 when gadget-Pong came out of a notebook with its bindings cut, and I diagnosed the symptom then without seeing that the shape of the import was the cause. One box fixes it because rekeying happens once for whatever is taken and stays consistent inside that record. The two properties pull against each other, so the check asserts both at once: what comes out still knows what came out with it, AND a second take shares no name with the first. Measured: four bindings all resolving inside the box; the second copy L915/L916/L917 against the first’s V901/V902/V905, nothing in common, its own bindings resolving inside itself. The other half is worth saying because it is not obvious: lifting a thing OUT of a box is a move, not a copy, so a world can be unpacked hole by hole onto the table and stay wired the whole way.

The movement is still wrong. I did forward 30, pendown, forward -30, right 30, forward -30. That should have produced only 2 segments with a 30 degree angle between them — not like the screenshot.

Two bugs, and the pen was telling the truth about both. A step was TWO messages — move across, then move away — each a move in its own right, so the pen drew an across-only stroke and then an away-only one: a right angle per step, with the net displacement perfectly correct all the same. A step is now ONE message, [move | position | [across | away]], with both legs filling in the numbers before anything is sent: one straight line per step, and half as many messages. And pendown FORGOT where the turtle was standing, clearing the last place, so the first move after it had nothing to draw from and drew nothing — Ken’s five orders came out one segment short and the missing one was always the first. Measured on his exact sequence: two strokes, 0.3 each, at 90 and 120 degrees. Why no measurement of mine caught either: they all asked where the turtle ENDED, and the end was always right — a staircase and a diagonal share an endpoint, and a drawing missing its first segment ends where a complete one does. The check now asserts the SHAPE: how many strokes, how long, and the angle between them. It earned its keep at once by failing with THREE segments, which was nothing to do with the turtle: strokes are plain meshes on the bench root, so clearing the table for a new world left every line from the last one lying on it. A world starts on clean paper now.

Next add 3D to the turtle (in a new example). The universal pattern is move plus roll/pitch/yaw in the turtle’s own local frame — BeetleBlocks, NetLogo 3D, NCLab, PiCraft all converge on the same three names from aeronautics. One thing to be skeptical of: most of them implement roll/pitch/yaw as sequential local-axis rotations rather than a single quaternion update, which is exposed to gimbal-lock-adjacent drift and order-of-operations sensitivity.

The warning was worth more than the vocabulary, so the frame is ONE QUATERNION, multiplied on the right by each turn and renormalised: right-multiplication is what makes an axis local, associativity is what makes a hundred small turns land where one big turn does. The three names are not three angles side by side, they are three ways of multiplying the same object, so there is no gimbal to lock and no order special-case. Measured rather than promised: ninety one-degree yaws give [0, 0.7071, 0, 0.7071] and one ninety-degree yaw gives [0, 0.7071, 0, 0.7071] — identical to four places. The message surface grew up, yaw, pitch, roll, forward and home; turns refuse the verb SET and say why, since a turn is relative by nature; pitch is nose-up for a positive turn as tilt-up means everywhere the vocabulary comes from. The pen climbs too — a stroke was a flat bar at one height and is now a bar between two POINTS, turned along the way the turtle actually went. The example, turtle3d.world, is a gadget with seven robots hearing words off the same kind of letterbox the flat turtle uses; a spiral staircase of move/yaw 30/pitch 30 draws three strokes climbing 0.846, 0.921, 1.118 and ends 0.392 above the table. A card in the world says the uncomfortable part out loud: the flat turtle works out its own sines and you can lift the lid on the sum, but a turn in space is an ORIENTATION rather than an angle in a hole, and pretending quaternion multiplication could be built from number badges would be a lie — so this frame is built in, as speed is, and the robots do the rest.

The two turtle worlds have the pad that is the turtle on the far corner of the desk. Maybe it is time to support the import of models — can you make a toy airplane and a dragonfly file so the user can put the 3D turtle behaviour on them? Vacuuming the 3D trail and removing it from Dusty produced a pad — it should be a new 3D object, and the 2D trail should work this way too. And after I vacuumed the 2D trail and had the turtle move forward, nothing happened.

Two new kinds, both ordinary things once they exist. A TRAIL: each stroke now remembers its own endpoints, so sweeping rebuilds the run as one object — segments relative to its own base, each keeping its colour and width — and out of Dusty’s bag it is a thing to set down, save, copy and sweep again; 2D and 3D are one code path. A MODEL: parts — box, sphere, cylinder, cone with size, place, turn, colour — deliberately nothing more, so the toy airplane is eight parts in a hand-readable file rebuilt from primitives with no loader. A model with a lid is live; examples/models has the airplane and a dragonfly, both facing heading zero. Measured end to end: import, drop the 3D turtle on it, pendown, pitch 30, move 30 — the airplane climbs 0.15, banks, draws its climb, and the swept trail of the flight survives a save alongside the banked plane. Imported things get FRESH NAMES now, as notebook pages give: importing one file twice used to put two things with one lid on the table — the copies-clash bug by another door. And “nothing happened” was the turtle standing against the table’s edge, ordered into it: the clamp ate the whole move silently. A move wholly absorbed by the edge now says so; one that partly travels stays quiet, because something visibly happened. The turtle gadget cards also moved in from the far corner to stand beside the bird. Thirty-three checks.

Please make another example program where one robot gives the bird 1/2, 1/4, 1/8 and so on and the other robot keeps a running total. Yes, let’s add the BeetleBlocks shape drops.

Zeno’s postman: two houses and a bird. The halver’s whole program is two ordinary moves — copy the fraction to the bird, drop a x1/2 badge on what is left — and the totaller’s is ONE: take the delivery off the nest and drop it on the running total, since a number dropped on a number adds itself. The total IS the arithmetic, no adding machine anywhere, and the check asserts the invariant rather than a tolerance: (2^k - 1)/2^k at every moment — measured 255/256, denominator a power of two, numerator one behind — which is why it creeps toward 1 forever and a child can read the missing part off the block. And the turtle is a dispenser now: [drop | sphere | 1/10] — or cube, tube, cone — lands a solid at the thing’s position and orientation in the pen’s colour, joining the pen’s current trail, so a sculpture of shapes and lines sweeps up as one thing and survives a save because trails already knew how to be things. Found on first drive: the what-list rejected “sphere” before the drop verb was consulted, so the first sculpture was one line and three swallowed messages. And the new checks exposed a leaked setting: pong’s pass had depended for weeks on a D.speed(2) inherited from the shelf check — the zeno check restored speed to 1 and pong “came apart” with flips exactly halved. Pong sets its own speed now: a check that depends on a setting must set it. Thirty-five checks.

I put the 3D turtle panel on the airplane panel but the turtle bird flew to the centre of the desk instead of the airplane. I tested activity1-even-numbers and turning on the add 1 house made all the houses active — that shouldn’t happen. Robots working in transparent houses should really perform each action, not just turn back and forth. And when a number is dropped on a number on a scale’s pan, let’s stack them instead of performing the operation — the idea is to see that 1/3 weighs the same as three 1/9ths.

The scale weighs piles now, exactly as designed: a plain number dropped by hand on a number in a pan stacks instead of calculating, and the beam discovers that a third weighs three ninths — measured tilting left, left, level, with the pan still reading 1/9 and the pile surviving a save. The first cut broke three golden worlds within the hour, because factorial and two activities have robots that count by fetch-and-op onto pan numbers — so the pile is the HAND’S gesture and a robot’s drop calculates as ever, which is the golden worlds doing their job. The glass-house robot walks its round: each step names the hole it touched, and the miniature visits each in turn, bows, and returns to the desk — the round still runs offstage in an instant, and the engine/view split stays on the wishlist. The bird lands where the mail is FOR: she flew “to the nest”, and a letterbox inside a folded panel has only the tray’s parked spot for a position — the middle of the desk — so a delivery’s visible landing is now the behaviour’s bound thing, the airplane. The activity1 report was measured and deliberately NOT changed: the consumers are authored armed, doze on empty nests, and wake per delivery — the semantics the bank canary depends on — while a house stopped by its lever provably stays stopped with the post piling up. If consumers should stay dark until their own lever, the world authors them stopped: Ken’s call. Thirty-six checks.

Thanks for catching the problem with my suggestion to stack up numbers on scales. Your solution is OK but breaks the idea that what robots do and what the user does on the desk should not differ. I suggested it for pedagogic reasons but now think it was a bad idea so let’s revert the scales to how they were before. Keep in mind the principle that training and directly doing should not differ.

Reverted whole — the pan-weighing helpers, the combine branch, the save and load of piles, the manual paragraph and the check. scaleTilt reads its two pans again and nothing else; thirty-five checks, goldens byte-identical, no trace left in the source. And the version I shipped was worse than the objection made it sound: when stacking broke three golden worlds I kept them green by gating it on “the hand’s gesture” — !busy && mode === ‘world’ — which reads as a tidy narrowing and is not one, because TRAINING is not mode ‘world’. Demonstrating a stack to a robot would have CALCULATED, and the robot would then faithfully repeat something the person never saw happen. The gate did not narrow the feature, it split the gesture in two, which is the exact seam the principle forbids. Written into BACKS where the next idea will meet it: what the user does by hand and what a robot does must be the same act, because a robot is trained by watching a person, so any gesture whose meaning depends on who is doing it cannot be trained — and a workshop where some gestures cannot be trained is no longer one language. Also kept: my response to a failing test was to add a condition until it passed; the tests went green and the language got worse. A gate added to make a test pass is a design decision in disguise. The pedagogy is still available without a special gesture — three ninths ADDED make a third — and if a pile of weights is ever wanted for real it wants to be a THING with a value of its own, not a special case in what dropping means.

I think robots in transparent houses should pick from stacks and use tools. But only display those stacks and tools it needs. I think the label on the side of the house with the switch isn’t needed. And when the roof is displayed let’s add the label to the roof.

A house now reads its robot’s program — and its team’s — and lays out exactly the stacks and tools those steps name: newNumber wants a number stack, newText a pad stack, vacuum wants Dusty. They are tokens rather than the real stations, a pedestal with a couple of cubes and a green cone for Dusty, standing along the back wall, and the round’s performance walks to them for exactly the steps that name them. activity1 is the perfect witness and became the check: Add 1 and Doubler both make fresh numbers and each shows a number stack; Split only swaps two birds, makes nothing, and shows nothing. An opaque house builds none of it, since a toy nobody can see into should not pay for furniture. Measured: the walk closes to 0.05 of the stack against an arrival threshold of 0.06. Still honest to state: the fetch is performed, not simulated — the round happened offstage in an instant and the walk is the account of it, and making them one event is the engine/view split. The name came off the lever wall, where it was printed across the arm with the knob in the middle of the word, and onto the ROOF, lying along the front slope. One trap recorded: paintRoomLabel runs before makeRoom, so WALL_TOP is not in its scope — the first version used it, passed the syntax gate, and would have thrown at the first labelled room.

Make an example of the airplane taking off and flying and doing a loop.

The toy airplane now has a world of its own, and the point of it is that a loop needs no counting. The tempting program had a takeoff phase, a climb phase and a loop phase with strides counted in each; none of it is needed, because a constant turn per constant stride IS a circle. The pilot’s whole round is three orders, always the same three — move 10, move 10, pitch 30 — with no counter, no phase and no comparison, so there is nothing to get wrong when a child edits it: change 30 to 20 for a tighter loop, to 0 and it flies straight until the table runs out. Two strides per turn widens the arc, so the plane runs, lifts and comes over the top rather than pivoting; twelve rounds close the circle. Two behaviours are bound to the one airplane and one SPACE starts both — the 3D turtle, which gives it move, yaw, pitch and roll, and the pilot, which speaks them — so the vocabulary and its speaker are separate objects you can open and change apart. Its pen is down, so it draws the loop it is flying and the flight path can be picked up afterwards. Two measurements shaped it: the first sizing (move 25, pitch 12) gave a radius of 2.4 and the plane flew flat along the two-unit ceiling; and a loop is a circle standing on its start, so it needs a radius of room BEHIND the plane too — the back quarter clipped the near wall until it was moved to mid-table. The check measures what a person sees: the drawn path must be as tall as it is deep (0.75 by 0.75), the plane must climb past 0.6 and come back under 0.05, and still be on the table at the end.

When I run the first infinity example I don’t see a bird leaving the Add 1 house to the other houses. I do see birds leaving the other houses to the nests on the desk. And the doubler and split robots don’t move despite the computation proceeding.

Both reproduced by measurement first: Add 1 walked 5.09 while Doubler and Split walked 0.00 apiece, and Add 1’s bird answers to a name whose only two nests are In (inside Doubler) and Input (inside Split) — neither on the desk. The performance was built from a value read straight after runProgram, but a robot dozing on a nest runs from checkWaiting, below it, when its mail lands: the two robots the activity is about were the two whose rounds the performance could not see. It is now built after the whole turn off a counter that only goes up, since runCount restarts both at Run and whenever a sleeper wakes. That fixed the build but not the sight of it — a house driven by post is busy for the one frame its round takes and quiet by the next, and the walk only advanced while the house was working, so there was no time in which to walk. A performance is an account of a round that already happened offstage; it is now allowed to outlast it. Walks went 30.3/0.05/0.27 to 30.3/14.4/5.9. For the bird: a courier flew mail across the table only when the nest stood on the desk, so house-to-house post fell through to the ordinary flight, which happens inside the sending house’s own tiny world at Instant. Couriers now cross the desk between houses, measured at 22 crossings. Three faults in the first cut, all caught by measurement: it fed only the first nest of the name and starved Split; it filled the air with 2384 birds, since letters land in order and a fast sender piles them up (one letter to a NEST is in the air at a time, and a second lands the first at once — counting per NAME instead cancelled one house’s letter with the other’s, since copies of a nest share a name, which bounds the count and keeps the pile in order); and a panel is a room too, so every order posted to a behaviour’s letterbox became a flight and the airplane’s pilot could no longer fly its loop. Also fixed: the airplane check sampled height every 35 frames against a 36-frame loop — it had been passing by luck. And the new check, “a house posts to a house”, measures the walk of every house and the distance a bird really flew, which is what the old glass-house check never asked.

The first 2 screenshots show the bird is gigantic… can you mute the app while you are running tests… When I paused the robots they turn back and forth — maybe we should think of pause as cutting the power… they appear briefly above or between the houses but their motion is so jerky it is hard to see any change.

Four notes, three of them consequences of making house-to-house mail visible. The bird was gigantic because the courier flies in the DESK’s world while a house’s whole interior stands at 0.11 — she was nine times the size of the house she was aimed at. Mail between houses is house-sized now, 0.30 against a house spanning 1.02, while a nest on the desk is unchanged. The jerkiness was the air cap: it made room by LANDING the earlier letter, so a sender faster than a 0.9-second flight cut every flight short — bounded, ordered and useless to watch. A letter posted while a bird is already in the air JOINS HER now: one bird flies at her own pace, carries whatever arrives, and sets it down in the order it was sent, so the pile comes out right by construction rather than by a rule. Measured on zeno: 107 frames in the air where it had been a blink. She does not tow it all — the halver handed one bird a tail of 241 pads, so four ride visibly and the rest ride along unseen. Pause now cuts the power: no swaying behind glass, no walking, no chimney smoke (stir 0.0000 paused against 110.6 running), though birds still finish their deliveries and the lever still swings. And the suite runs silent — not via setVolume, which would have written the mute into the workshop’s own saved preference from a page Ken never opened.

If a user imports an MD file then render the markdown on the text pad.

A pad’s paint centres every line in one size, which is right for a poem and wrong for a document. A pad can now be told it holds markdown, and is laid out as a page: left-aligned from the top, headings in their sizes, bullets hanging with their nesting, numbered lists, quotes ruled down the side, rules ruled, fenced code in a mono face on a tint, and bold, italic and code read inside a line — at the largest type the whole page still fits at. Only as much markdown as a pad can honestly show: tables, links and images read as their own plain text rather than disappearing. The mark lives on the PAD, not the file, so it survives a save, a copy and a robot handing the pad to a bird — and it is restored BEFORE the words, since the first cut rendered the import beautifully and brought it back from a save as centred grey.

The markdown rendering is working but it is blurry and too low contrast. For zeno example I saw a few good sized birds fly from the halver to the totaller but then the totaller produced a value with 38 digits and a stack that kept growing (over 3000 numbers on it) This despite pausing the robots.

The blur was resolution: a pad’s face is 512 across whatever size the pad is, and a document pad is 2.5 tablets wide, so the same texture was stretched over two and a half times the table. The canvas follows the pad’s size now and a page gets half again on top — 512 became 1920 by 1468, with anisotropy doubled since a pad is always seen at a glancing angle. The contrast was the pad’s navy, a colour chosen for one word at forty pixels which reads grey under a page, plus 340 fibre flecks of grey and white behind small type: a page is inked near-black on clean paper. The three thousand were not numbers but queued animation steps — every delivery enqueued a four-step tuck, and zeno’s halver posts as fast as it runs while the totaller takes one a round, so the queue reached 2983. That is also why the pause looked broken: houses do stop when paused, but the queue keeps draining so the user’s own actions can finish, and what was draining was two thousand deliveries. A delivery arriving into a backlog is now tucked rather than performed, the first letter of a landing still flying properly because that is the one being watched. The same fix cured the pile: restacking is what hides all but the ten a nest shows, and it had only ever run at the end of a tuck queued behind two thousand others. Measured: queue 2983 to 0, visible pile members 89 to 10, growth while paused +93 to +0. The nest still fills up, 162 waiting, because the halver really is faster than the totaller — zeno’s own arithmetic, honestly displayed.

Why do you need much more clock time to make changes than earlier? Would restarting the Claude app help? zeno is working better… when I typed “.” to the halver house it kept running. The readme.md in the behaviors folder renders like screenshot 2 - not so good. Maybe when there is too much text to fit on a text pad it can be viewed as having multiple pages.

Three answers. The clock time was my own tool use: every probe file written into the project opened a browser tab that was never closed, and eight were live at once by the end, each holding a renderer — reads that took a second were taking forty-five and two suite runs never returned. Closed, the same probe answered in seconds. The house that would not stop: a house’s turn ends by working out whether there is more to do and assigning it to dirty, so a “.” arriving mid-turn was undone a moment later. The end of a turn now respects a stop — three rounds at the stop, three rounds six seconds later. And the README: shrink-to-fit is right for a poem and hopeless for a document, so a page is now laid out at a size meant to be read and what does not fit starts the next page, numbered in the corner, with ] and [ turning the page you point at. One markdown rule mattered more than the pagination — consecutive lines are one paragraph. Most READMEs are hard-wrapped at seventy characters, so every source line had become its own line, broken mid-sentence, with emphasis spanning the wrap left unread as literal asterisks. Joined, the same file went from 44 pages to 23 and started reading like prose.

It doesn't matter whether I enter the totaller house while halver is running or I stop halver before entering and restart it after entering - in both cases I can't turn off halver.

That second message is what made it findable: the condition was never the order of the steps but whether a robot was mid-round when the key was pressed. Standing inside a house whose robot is working puts the current world into replay — entering starts that robot on purpose — and two separate guards then fire, one for each way Ken tried. The keydown handler ran only when the mode was not replay, so SPACE and “.” did nothing at all; and runRefusal answered the lever with “one robot at a time”, a rule about the user’s own desk that was never meant to cover a house standing on the table. Both are lifted for switches: a house and a behaviour are their own domains, and houses have always been allowed to work while you work and while another house works, so switching one is not starting a second robot at your desk. What a robot is working ON stays off limits while it works. Measuring it needed the same care as finding it — a check that samples between rounds sees “world” and proves nothing — so the probe drives frames until the mode is replay and presses in that very frame: stopped=true, 0.0 rounds/sec. Also this round: the 180-degree turn of an entered house, which Ken chose and I implemented, measured wrong and was reverted — inside a house the robot already faces you, and the turn showed its back. What is hidden is its desk, not its face.

Turning the halver house on and off is working. But the point of entering the totaller house is for the user to observe how it works. Seeing his back isn’t helpful. And I don’t see the robot taking numbers off the nest stack and dropping them on the number. Entering houses used to look very much like when training a robot or running a just trained robot - why can’t we restore that?

It could be restored because it was never gone: the tableau inside a house always was the training tableau — same middle desk, same work spots, same robot body wearing the house’s name — and what differed was the camera. The door’s zoom lerps the camera 35% of the way toward a house standing on the table, which ends low and close, and nothing ever restored it; from down there the robot’s own body hides its desk and the work spots laid out behind it, which is the whole of “seeing his back” and of the invisible nest-to-number round. Training looks right because the workshop camera is high and looks over the robot’s shoulder. The door now finishes the job: after the swap the camera glides to the workshop’s own vantage, and the exit door does the same on the way out, where it used to strand you wherever you had orbited to inside. Measured: the camera lands at 0.40/3.05/5.45 exactly, and nine seconds inside the totaller shows eight rounds performed visibly — the robot taking the top of the pile and dropping it on the total, on camera. This round also took back a wrong fix: the 180-degree turn of the entered world, which showed the robot’s back to fix a problem the camera owned all along.

When the robot takes the number from the top of the nest stack it just magically appears in its hand. Let’s animate something that indicates taking an object off a nest stack. If the stack is too tall then approximate it but otherwise have it reach for the top number and grab it.

The take already walked to the nest and opened the claw, but the arm only ever went to the one desk-height pose and the top of the pile swooped down into it. The grab pose is now aimed at where the top actually stands, interpolated between the desk reach and the full copier stretch by the pile-top’s measured height — both heights measured off the template robot at boot the way reachLocal always was, rather than guessed. The pose is filled in after the walk, since armTo reads it late and mail can land mid-walk and change where the top is. “Approximate it” falls out of the clamp: a pile taller than the arm is grabbed at full stretch, the thing crossing the remaining gap in a grasp settle lengthened in proportion, so a long grab reads as one rather than a snap. The claw became measurable at the same time, so the proof is a number: over twelve seconds of the totaller’s rounds the claw peaks at y 1.17 against a resting 0.40, with the pile top at 1.06 — a fixed desk reach peaks near its floor.

In the screenshot you can see the robot is reaching to the wrong place to take a number from the stack. Also my first and third test the robot was faced away from the user. The second one was fine - not clear what the difference is.

The height fix raised the arm but never moved the aim: the robot walks to where the claw lands at the DESK pose, and the interpolated grab pose puts the claw at a different horizontal offset, so the higher the pile the further from it the claw arrived. The grip is now measured in full at both poses, standForPoint takes the offset of the pose that will actually reach, and the whole decision — where the top stands, the pose that meets it, where to stand so that pose lands on it — is made in one place when the walk starts. Measured over 27 grabs: worst claw-to-pile-top distance 0.284, part of it the half-height of the grabbed thing itself, where before the arm could be a full desk away. The facing had the same shape as every intermittent bug this month: a dozing robot glides home in x and z but kept whatever yaw its last walk gave it, and the scratch spots are behind — so whether it dozed with its back to you depended on the program’s last step, not on anything Ken did differently between tests. The glide home now turns the robot home too, shortest way round: the dozing robot faces the eye by 0.89.

fix the bugs you listed and notebook copy on access by a robot

Four bugs, two of them closed by measurement alone. The reach ceiling verified: a pile six deep with its top at 1.65 and the claw peaking at 1.76, past the old 1.17. The desk inside a house measures z +0.58 between viewer and robot — the “work behind it” listing was a leftover from the rotation detour. The multiple thought bubbles no longer reproduce; they were the runaway scheduler’s work, fixed with it. The extra-copy undo took finding the right gesture: drop a gadget into another gadget’s OPEN tray, undo — tray interiors are deliberately not rewound, but the snapshot rebuilt the pilot from a spec while the original lived on in the tray, two things wearing one live name. The missing invariant: a live name is never rebuilt while its owner stands. buildThing now reuses the registered node from wherever it got to — and must not require it to be in the scene, since mid-restore the tray holding it is off the table at exactly the wrong moment; the first cut tested inScene and still made twins. Measured: one pilot after undo, on the bench, binding intact. And the notebook: each round’s first read snapshots the pages, so the user can hold, flip or edit the real notebook mid-run — a run used to die with “there is no notebook here” when it was in the user’s hand. Writes still go to the real notebook, because filing is how a robot publishes and a private copy that evaporates would lose work silently. Measured: five rounds of sevens read to a total of 35 while the notebook sat in the user’s hand.

Here is how far it got: ..cp.d trips done — the suite stalling at the copies check in every browser, after the bug-fix round.

The stall was real and mine: the Instant-exemption for the sibling rule had resurrected the ticker runaway inside the inner g-loop, which ignores the once-per-turn gate as its licence for nested pipelines — so the same neighbouring ticker ran fifty times per g-loop, per afterQueue, per frame. The profiler named it: 1.2 seconds of room work per frame and 3615 registered numbers. Containment took three cuts, each falsified by the goldens: once per turn starved pipelines, dirt-as-discriminator left the same lever up, a cap of three visits holds. Two real bugs surfaced under the same light: the cont tail asked “is there still work” globally, so two mail-partnered houses held each other dirty for ever — it now asks only within the house’s own world; and a dozing room re-dirtied by a final delivery clears only after its 30-frame sleep-cache, so the harness quiesces 40 frames before dumping. The suite learned to run anywhere: setTimeout yields when visible (a MessageChannel ping-pong starved paint and input, and Chrome offered to kill the very tab the yields protect), MessageChannel when hidden (setTimeout is clamped to a second there), ?block=1 for headless, and the paced-house check counts real seconds rather than virtual frames, having passed only while the yields happened to be slow. End state: ok true, 41 checks, 13 goldens byte-identical — with the undo-twin fix, the notebook copy-on-access and their two new checks inside.

Robots reaching for the top of the nest stack is much better but not as good as possible. I think we should stick with the principle that robots can do what the user can do — writes should apply. I think panels should have a door. When I drop a panel on a panel it doesn’t get smaller and end up part of the panel underneath.

Panels now carry the same door a house has, and walking through it is the same enterRoom: the panel’s world at full size, robots running where you can watch them, the tall door back out — measured at worlds-deep one inside and zero after leaving. A panel dropped on a panel nests whole: card and tray both onto the group’s bench, shrinking with its world to 0.11, the binding unchanged and independence restored by lifting it out. Finding where to fix that was the work: the park-it-beside rule existed in three copies, and the first fix measured a clean zero because a catch-all sitting ahead of everything ate the gesture first — all three now route to one source of truth. The reach: a pose-table aim was built, measured worse than the lerp it replaced, and honestly taken back out; the lerp is the “much better” baseline Ken judged, kept until the kinematics are done once in one place. One durable find from that detour: actionTake shadows window with a boolean, and a debug write to window.__aim crashed the room from inside. And the notebook’s write-through choice is ratified: robots can do what the user can do, like a program writing a file.

The robot reaches up which is good but if he’s going to use that arm he should move over so his hand is near the stack — this would also fix the released number floating over. The totaller robot ignored the stop button. I see numbers being added to the nest stack but don’t see any birds doing the delivery — why should any bird deliveries be queued at all? I dropped the 3D turtle panel on the airplane panel and used the knob — the bird flew to where the panel used to be, and the plane was not updated until I removed the turtle panel.

Four fixes, each reproduced by measurement first. The robot now stands where its chosen pose’s claw lands on the pile — one decision the stand and the arm both follow — measured dead-on (0.000 off at the grab and at the release; a too-tall pile is reached at full stretch directly underneath). The lever judged on/off by the dirty flag, and a mail-driven house is dirty only for the instant a letter lands — so “stop” took the start branch; the switch now remembers being thrown, and stops a dozing house you set going (two subtler rules failed first: hydration itself leaves every fresh house with a dozing robot and one settled round, so neither the doze nor a round count can tell “running” from “new”). The post is paced by its own delivery: a house that sent a courier waits until the letter is on the nest before its next round, so no backlog can build — five stragglers used to land after the halver was stopped, now zero, one visible bird at a time. And the knob’s fold judged a panel by its own work and serialized the live turtle panel nested inside — letterbox out of the scene, orders with nowhere to land; a fold over live nested work now keeps the tray alive on the bench, and a bird whose letterbox is hidden comes down on the thing the behaviour drives, not the panel’s parked spot. The best bug of the round was in a probe, not the app: the airplane world’s own example boxes include two pitches, which turn without moving, and “boxes on the bench” measured those — three cycles chasing a phantom while the plane quietly obeyed every message it got.

Could we make it so that Marty can be asked to produce new resources that appear in the world? Could the API be used to request a new 3D model (like the airplane and dragonfly) and then import it? Perhaps the Marty dialog panel would need an additional button for asking for media. … Yes, go ahead with the models. Later I think we should use turtle graphics for the procedural images.

It turned out not to be a text-to-3D problem at all, which is why it was a day’s work and not a month’s: the airplane and the dragonfly are not imported meshes but parts lists — eight entries of shape, size, position, rotation and colour — so asking for a new one is asking a language model for a small piece of JSON, which is what they are best at. Marty’s panel gained a Make button beside Ask; type “a red sailboat” and it lands on your table as an ordinary thing you can pick up, copy, bind a behaviour to and save. The rule he keeps is the interesting one: he makes nouns and never verbs. His orders have always forbidden designing programs for the visitor, and a prop is the opposite of a program — a sailboat that does nothing is scenery asking to be programmed. Nothing an answer says is trusted: four shapes only, every number finite and clamped, colours put to the browser’s own parser, forty parts at most, and a size a hand can pick up — which the first screenshot proved has to work in both directions, since a toy answered in centimetres is as unusable as one the size of the table. The check feeds the builder canned answers rather than a network, because the risk was never in the network.

The text entry area says “Ask, or ‘show me birds’” - it should instruct to use the make button when not asking. The “Ask” button doesn’t have a tooltip. After it created something I prompted “good but it should have 6 legs” and it didn’t take into account the previous “Make me:” prompts.

The third one was a real mistake and a deliberate one: the maker was given no memory on purpose — threading the chat through it made models answer in prose about a thing instead of building it — and iteration went out with the prose. But making is iterative by nature: you ask, you look at what arrived, and you say what is wrong with it. The maker now keeps its own memory one exchange deep, holding the parts rather than the chatter, so “give it six legs” revises that insect instead of building a second one — and the revision takes the old one’s place on the table, unless you have already picked it up or filed it away, in which case it is yours and he leaves it alone. The box now reads “Ask, or type a toy for Make” and Ask has a tooltip. The sharpest lesson was about the test: the check covered the builder, because that is where the risk was imagined to be — the memory was the one thing the seam did not reach, and the one thing that was wrong. The seam moved to cover everything that happens once an answer arrives.

Once again I saw a robot facing away when entering a house. … The attached world responds very slowly despite no robots running. … The world isn’t slow when I refreshed and loaded it. But it was very sluggish when I saved it. I think the scheduler should let each robot do a full round every cycle regardless of how many steps it takes.

The old note insisting the house’s world is not turned round was right, and stopped one step short: the glass-house performance turns the mini robot toward each hole its round touches, and when the round ends it walks home facing the way it travelled and stops there — so a return from the left left it looking off to the right for good. Five entries in ten, settled at −138°. It squares up to the desk now, and turns round to greet you if you walk in mid-round. The first attempt measured zero change, because a bot has both a node and a root and the eye sees the one the fix wasn’t moving. The attached world (3,840 numbers on one nest, denominators up to 1,309 digits) was costing 77ms in a single frame twice a second with nothing running — the detail sweep asked every hidden number where it was in the world; it now measures only what is on screen, and the same world runs that sweep in 0.1ms. The live sluggishness Ken felt while it ran was worse and separate: restacking a nest hid every member of the pile on every delivery, quadratic over a run, now ten. And the scheduler rule is adopted: budgets decide how many robots get a turn, never whether a round finishes — only the runaway watchdog can end one early.

I see “That came back as something I could not build…” after asking for “a 6-legged preying mantis”. I tried twice with Sonnet and once with Opus. It worked with several GPT models. Gemini replied “I could not make it — Gemini said 503.” Maybe API errors should be logged to the console.

The provider split pointed straight at our own code: the OpenAI and Gemini branches send no token cap, Claude’s sends one, and the maker asked for 1600 — so a mantis (body, head, feelers, six legs, twenty-odd parts) came back cut off mid-array and unparseable. Nothing was wrong with the model or the wish, and the message blamed the child for a limit we had set. Now: four thousand tokens; a parser that takes the first balanced object rather than the first brace to the last, so a sentence after the JSON no longer ruins it; and when the braces never close, the parts that did arrive whole are salvaged into a toy that says honestly it came up short. That salvage found nothing on its first try, because it stopped at the first unbalanced object — which in a cut-off answer is the outer one, holding everything worth saving. And the console, as asked: every refusal logged with provider, model and error, every unbuildable answer logged with its raw text, and a 503 told apart in what Marty says, since the mothership being busy is not the child’s fault.

As I’m doing the testing can you add a “draw” button like the “make” button that generates images as you suggested earlier.

Turtle graphics, which was Ken’s own choice a round earlier and the right one: children already learn forward, right, left and the pen from the turtle behaviour, so the language a picture is written in is a second use of words they know rather than a new notation — and the picture stays legible, since a snowflake is visibly six of something repeated. It is also the only kind of picture that works everywhere, because a turtle program is text and text crosses every wire, while real image generation needs an endpoint Anthropic hasn’t got and a host the artifact frame refuses. The interpreter records strokes rather than drawing as it goes, so the finished picture is measured and fitted to the paper — a turtle cannot know how big the page is. The guards are the maker’s, and they hold: a doubly-nested repeat of a million stops at 13,329 strokes, prose draws nothing, a script for a colour is not a colour, and unknown words are stepped over so a flourish cannot halt the drawing. Best of all, a turtle program degrades gracefully — last round’s truncation problem becomes “the turtle ran out of breath” and a shorter picture.

I’m not very happy with how Dusty looks. It doesn’t have the charm of marty, ruby, and robots. Try a more appealing design. … do it properly … one more pass on the mitts, bag and glow … I’m happy, go ahead.

Eight versions, and the instructive part is why the first four failed: each faked its face by laying dark shapes on the shell — a visor slab, a torus meant as a groove, an ellipsoid for a mouth — and each read as an appliance with features glued to it. A torus sits proud of a surface, so it cannot be a groove; an ellipsoid laid over a sphere cannot be a hole. A real opening has a rim, a wall and a shadow, and none of those can be added by putting something on top. One version came out with no mouth at all, because the intake ellipsoid was centred 0.06 short of the body’s own front and never broke the surface. The fix was a boolean: cut the mouth and the eye sockets out of him. After that the errors were legible and quick — a throat poking back out of the hole it had just cut, pupils sunk at the eyeball’s own depth so he stared at the floor. The last pass turned up one real discovery: the bag was invisible because it was coral on a coral body, which has no silhouette from three quarters behind. Swapping him in needed nothing else; the app never used his intake anchor, and his gaze still lines up with the bench to a dot product of 0.99.

There should be a way to return the info notebook — maybe the (i) changes to indicate return the notebook. Dusty is good but should be facing the camera when nothing is held, otherwise the “hand”. Ruby and Marty too. … Can the JSON be formatted to make it easier to read and edit? … Marty should look at its dialog panel when the user is typing or the cursor is over it. … I think Marty’s eyes can be better — instead of white eye balls let’s go with blue.

Six small things, and the instructive one is Marty’s panel. The plaque that hands out a thing’s info notebook now shows a return arrow while the notebook is out and takes it back on the next press, wherever it wandered to — what a control will do next is written on its face. Dusty, Ruby and Marty turn to the camera when your hand is empty and to whatever you are holding when it isn’t, eased rather than snapped. Saved things are formatted as documents: structure indented, numeric arrays kept on one line and short objects collapsed, so a part is one readable line and Ken’s save-edit-import route works by eye. Marty watching his own panel took three attempts, and the first two were wrong for one reason: a panel is a sheet of glass over your view, so every honest unprojection of it lies on the line from the camera into the desk — and from where Marty stands that line is your face. Unprojecting at half depth moved him not at all; two metres out along the same ray moved him 1.3°, the wrong way. What you actually see when someone looks at a panel on the left of your screen is that they look to your left, so he now aims at a place beside the camera, out along its own right-hand axis by where the panel sits across the screen: measured 9.5° toward it on hover and on focus, back to his idle heading when you leave. The check asserts the aim rather than a number of degrees, which would only measure the width of the test frame. Blue eyes at last, and one retry for Gemini 3.7’s 503 — we send no thinking parameter, so there is nothing of ours to correct, and guessing an untestable request shape is not a fix.

Dusty’s eyes are still white. The totaller robot’s arm motions after entering the house are better but the number it grabs and drops isn’t visible. But it is dropped and the addition happens. Enter should display a number (or other objects besides pads) as the camera zoomed in on it. And the arrow keys for rotation should still work. No need for wiggle feedback after pressing enter for a closeup view of anything.

The invisible number was last round’s speed fix coming back: a nest now remembers the ten members it last showed, so restacking costs ten visits instead of one per letter ever delivered — but the top of the pile is exactly what a robot takes, and detaching restacks while the thing is still hanging on the nest, so the memory hid the number at the moment the claw closed on it. It reappeared only where it landed, which is why the addition worked and the carry did not. Two false starts, both the same error: a fix that guarded on parentage (true at exactly the wrong instant, kept only because it catches two nests merging), and a reproduction that counted every invisible number not on a nest — 1603 frames of them, nearly all the halver’s stashed world, legitimately hidden while you stand inside the totaller. A measurement that cannot tell the bug from the world working correctly is not a measurement. One line of debug — what does the claw hold, can it be seen — reproduced it in a world with no houses at all: 513 carried frames, 513 blind. Cured in detach; 513 carried, 513 seen. Enter now flies to anything: a pad is still read from straight overhead, and everything else from the front, at the bearing you were already watching it from, lifted 17°, as close as it fits — measured 0.75 m on a number, with Escape landing back within a hundredth of where you left. The arrows turn it there, quarter by quarter, keeping the writing upright, which is the whole point: a number says the same value six ways and five of them could not be read without picking it up. Nothing shakes in a closeup any more — the wiggle refused to start there, but it is only consulted when the pointer moves, and after Enter it never has to. And Dusty’s eyes: cream balls with a pupil glowing hard enough to blow out white, which is why giving Marty blue eyes left Dusty looking exactly as before.

The app froze when I placed a generated model on the copier. … I think the operator should not obscure the display of numbers — move it to the upper corner. … Somehow [Dusty’s] eyes are a bit creepy. Maybe his eyes should be more like marty and ruby just a different color than black.

The copier knew how to copy each kind of thing, written out by hand — and then an else that made a box. Not “if it is a box”: an else, so every kind nobody had thought of arrived there and was copied by reading holes it does not have. A model has parts and no holes, so the read threw — and it threw inside the step that lowers the copy into the tray, which is why it froze rather than complained: an exception in a queued step leaves that step half-run, so the queue never advances and every later click waits on a scan that will never end. The workshop doesn’t crash, it stops. The catch-all is now named, and anything with no branch of its own is copied from its own written record — whatever a thing can save, it can be copied — which closed trail too, the same hole nobody had hit yet. The raw record, mind: the full one carries the live name, and the builder hands back the registered thing itself when it sees one, so copying by the full record would have returned the original and called it a copy. Mimi now says so rather than dying inside her own scan. The check turned up a fourth thing Ken hadn’t seen: the parts list was sliced as a list and shared as objects, so a model and its copy held the same parts. The operator badge was painted after the face, so wherever it sat it won — at radius 30 it reached row 84, and a long number starts writing at row 56, which is how the plus sign came to lie across the first line of a monster fraction; at radius 20 in the corner it ends at 56, with the writing measured starting at 85. And Dusty’s eyes: Marty and Ruby share a plain ball with a small pupil just proud of it and no highlight; Dusty’s had a pupil at 53% of the ball, lit, with a hard white spark on top — the recipe for a googly eye.

I think even very large integers should be displayed in English on one face of the cube. The app froze when I tried to train a robot with a model. It couldn’t pick it up and then it froze.

The copier’s else that assumed a box had two siblings: the picture in the robot’s thought bubble, and the same thought in words. Both read the holes a model has not got, and both run in the same breath as the click that hands a robot its lesson — so the throw left the workshop mid-gesture, a lesson begun with no thought to show for it, and nothing answering afterwards. The shape of the mistake is the lesson: a chain of else if (kind === …) ending in a bare else is a promise that no new kind will ever be added, and models and drawings were added months after those chains were written. Underneath was something quieter and worse: the matcher had no rule for a model and its tail returns “no”, so a robot taught with Ken’s boat would not have recognised that very boat — the lesson would have been wasted even once it stopped crashing. And the numbers: the scale names stopped at decillion, so anything past ten to the thirty-sixth fell out of English into scientific notation, which is the one thing a child cannot read aloud. The names now run to vigintillion, and past even those a number reads as “about five point seven times ten to the power of sixty-nine”. The subtler half was the face rather than the words: a sixty-digit number’s real name is eight hundred characters, which on a face this size is a grey wall ending in an ellipsis — the number hidden in English rather than displayed in it. The face now falls back to the short reading only when the full name will not fit at any size, so a thirty-six digit number goes on saying itself in full.

why does this face have “...”? … when the English doesn’t fit on a face let’s have shrinking letters like shrinking digits so the first and last parts are shown. … if a number cube has been rotated by the user it should stay that way when released (or return for closeup viewing). … You can use the way scale names are generated from Latin to handle much bigger numbers. … control-c while holding a number cube should put the top face text on the clipboard.

Four asks, and two of them are the same thought: what you did to a thing belongs to the thing. A face too full kept its first lines and put an ellipsis on the end, so a nine-hundred-digit number showed its beginning and threw its end away — and the end of a number is as much of it as the beginning; it now works the way the digits face always has, head, gap, tail, with the lines either side of the gap set smaller so the break reads as a break. The scale names are built rather than listed: a table stops wherever its author got bored, and extending it by hand to vigintillion last round was the same mistake with a longer table. Past a nonillion English makes its names out of Latin numerals to Conway and Wechsler’s rule, and the subtlety is all in the joins — “tre” grows an s, “se” an s or an x, “septe” and “nove” an m or an n, depending on what follows, so the word can be said aloud. Spot-checked against the dictionaries: ten to the 63rd is one vigintillion, the 93rd one trigintillion, the 303rd one centillion. A turn now survives being put down, through the field that already meant “this is how this thing points” and which the saved world already carried. And Ctrl+C: a face is a canvas and a canvas is not text, so there was nothing to copy — every face now records its own wording as it is painted, and the copy takes whichever face you have turned toward you.

Chrome’s Gemini Nano isn’t very capable but can it make any models? … The tooltip for dropping on a robot should be different for untrained and trained robots. I trained a robot to copy the unicorn model and it did fine creating many extra platforms. But when I stopped the training all the objects on the extra platforms ended up on the desk. Remember that while a robot is in its thought bubble that is its imagination so no changes remain after leaving. When holding a model the up and down arrow should work as well.

Nano could always make models; it was being told to answer in the wrong shape. The brain built into Chrome is small, and the one thing that makes it usable is constrained decoding — it is told what shape its answer must take — and it was handed the chat schema whatever it was asked. So pressing Make produced a perfectly well-formed conversational reply, the maker failed to build it, and the console blamed the child for it. Three errands, three schemas, and the errand chooses: told name,parts it makes a model, told name,orders it draws. The unicorns were not a leak. Four ways of making copies inside a lesson — onto fresh work spots, onto the table, left on Mimi, left in the claw — all rewind to exactly the world you came in with, and that is now a check. What Ken watched was a run, whose work is real and meant to stay. The real fault was that nothing said which of the two had just happened: a lesson ending and a run ending look identical at the moment the robot stops. Both say so now — leaving a lesson says the table is as you left it, and a run that sweeps its work spots says how many things it put on the table and that they are yours to keep. A rule nobody can see is a rule nobody can rely on. And the tooltip now says what will happen to the robot in front of you rather than making you do the case analysis; tipping, refused for everything but a number on the grounds that only a number has six faces worth reading, now works for a made thing too — a unicorn has a top and an underside.

I’m thinking about puzzles in ToonTalk. … I’m now thinking puzzles shouldn’t be a new capability. Instead they should be creatable within ToonTalk 3D. … Puzzles should occur in a constrained world … a goal that is visible to the player … a way to submit a solution … the action taken is typically to replace the puzzle by the next puzzle … a puzzle author should be able to train a robot to do the desired actions … a way to start over easily. Marty should be able to provide hints. … Can’t each puzzle be a world file and a robot can load a named world file?

The original was read first — puzzle.cpp and the seventy-four .pzl files of the tutorial, each an intro, a saved room, a goal object, four permission switches and escalating hints ending in the whole walkthrough. A third of its goals are behaviours, judged by special cases with timed waits, which settled at once that a scale can only ever be the commonest program a judge runs, not the mechanism. Everything else composed out of what the workshop already had. The goal is a thing with fixed on it — shown, never taken. The submission is a bird whose nest is inside the judge’s house: no new gadget, since giving a bird your answer is the thing every child here already knows. The judge is a robot team in an opaque house dozing on the post nest the way Zeno’s totaller does; the leader’s thought is the goal, and the team behind it recognises any box, any number, any pad and sends it home to a nest labelled “from the judge”, which is the whole of the feedback. Rules ride on the world file per puzzle, as the original’s switches did. The one robot step that did not exist is load, a world by name — with a library field bundling successors inside a file, since a published artifact can fetch nothing. Two things went wrong: a house’s own world comes through the same door as the puzzle’s and wiped its rules a moment after they were set; and a robot asks for the next world from inside the world about to be replaced, so the request is honoured at the top of a frame — where the suite caught that its own frame driver did not do what the real loop does. Puzzle 1 runs end to end and is a check.

I didn’t see a message after solving puzzle 1 (I guess it was reset too quickly) but puzzle 2 was fine. The layout could be better: the bird could be central and the objects to be used can be closer to the camera side of the desk. … Instead you can add a button for going to the next puzzle and one for starting over. After doing all this create several more puzzles.

The note was in the air when the table changed under it: the judge’s last two steps were “give the bird the note” and “open p2”, and a bird takes a second to cross the desk. In a puzzle the load step now offers the next world — it arms a Next button and says so — and the player presses it when they have read the note; outside a puzzle the step still opens the world at once. One layout rule for every table: what you work with across the front, the bird in the middle with the reply nest beside her, the goal and the judge at the back. Three more puzzles after the originals: a box with 8, 16 and 32, which teaches that boxes join by dropping one on the side of another; a zero, made by a 3 wearing a minus badge since the keyboard is off; and a box of two zeros made by a robot you train with Mimi, six steps allowed. Every later puzzle rides in the earlier ones’ libraries, so the set travels as one file, and a check loads all five and asks each judge from outside its house whether it would accept the very goal on its table. Deliberately not built: the original’s “a number bigger than 1,000”, the first to need a judge that weighs rather than matches — a scale inside the house and a second round reading its tilt — which is the enhanced-scales round and deserves its own measurements.

I tested puzzle 1 by giving the bird [2 | 1] and it came back. OK so long as also a message also comes back … it would be better if it explained that the order of the contents matter. There is an undo bug … it also restored a copy of the original contents on the nest. … I dropped a 1 on the box on the nest and it was added to the 3 (now a 4) far away. … a button for reading the contents … “front or behind” should be left or right … a not-very-helpful tooltip that should be about joining boxes … only puzzles that can be solved in a way that is a bad algorithm should have a maximum number of steps … inside the judge house … I heard repeatedly that the judge didn’t match … the robot should doze.

Two of those were one bug, and it was old: the walk that finds which hole a thing sits in searched the stations and the bench, and a box delivered by a bird sits on a nest. A number lifted out of a box on the reply nest was never struck off its hole — the box went on claiming a number now in your hand, a drop across the table changed the box’s reading too, and undo rebuilt the pile from a record that still listed both numbers. One line: the piles are roots. The judge nagged because of a wildcard — wild insists something is there, the note pad’s hole was empty once it had been sent, and “no” beats “wait”; a null in a thought is a hole never looked in, anything or nothing, and the judge dozes now. A wrong answer comes back with a note the judge copies on Mimi — she stands in every world — so it is never used up. And the smaller asks: the box-over-box tooltip names the side, the manual’s “in front / behind” became “left / right” (which is exactly what Marty was quoting), Marty’s puzzle context says boxes are matched in order, a held pad has a Read button, and a step cap is announced when the lesson starts — with a pointer to the Trained actions panel the first time — and only where a lazy algorithm would otherwise do.

We should replace the “Start” button with “Free Play” and “Puzzle Game” (and maybe something about the infinity exercises too). If the player has completed some of the puzzles then the “Puzzle Game” should provide the choice of continuing or starting over.

The card at the door now offers Free play and Puzzle game. Puzzle game opens the first puzzle, or — for somebody who has been here before — says “You were on puzzle 2, with 1 solved” and offers to carry on or to start again from the first; where they got to is kept per person in this browser beside their notebook, written when a puzzle opens and marked solved the moment the judge offers the next. The set has to travel in the page, since a published artifact can fetch nothing: a small script embeds the first puzzle, which carries every later one in its library, beside the embedded manual, and the app reads it at boot. The infinity activities stay outside the door for now — they are sheets that open the workshop from outside. And a suite bug worth its own line: the verdict’s overall flag was an AND over the checks that existed when it was written, so the nineteen added since reported in the log and were ignored by the verdict, and a run could say ok over a FAIL for most of a day. It ANDs everything now, and the puzzle check it had been hiding is green once its waits read the nest after the notes land rather than the instant the flag flips.

There is too much overlap between what Marty is saying and what the workshop panel is saying. Dropping +3 on −3 ends up with −6 — that doesn’t make sense. I wonder if we can make Mimi more of a character. After the robot is run and makes [0 | 0] you hear advice about making the robot more general — confusing here. Time to do more puzzles. The backstory of the puzzle game was good in the original; if we keep it we need to indicate that Marty’s ship has been damaged. … Surely it isn’t prime. … the full English with the middle shrunk … after entering the number and escaping its orientation isn’t restored … control-c read out all of the digits.

One voice for the story: Marty tells you what is wanted and the card keeps to where you are and what the controls do — as its idle line, since the idle line is what gets written back the moment your hand is empty. The −6 was the badge model showing through: a 3 wearing a subtract badge, plus 3, is 6 under a minus; the workshop’s own rule is that the minus key negates, so puzzle 4 hands out a real −3 and either drop makes 0. The advice after a run is offered as a possibility — “if you want it to work in more situations” — rather than a correction, since a robot that stopped has often just finished. Puzzle 6 is the post: there is no Rounds control, a robot runs until its thought stops fitting, so the original’s “double until 1,024” cannot stop itself here — but a nest can: add up the numbers on it, which is the first puzzle that needs Ruby and the first whose end is the robot going to sleep. The ship is a made model lying on its side at the back of every table with its nose scorched, and Marty points at it. A power of a prime is no longer called prime. The words face shows the whole name, head and tail with the middle closing up. A cube turned in the closeup is square on the table after Escape, the line-of-sight roll having been the hand’s and not the table’s. And Ctrl+C says “733333333… and 111 more digits”. Mimi: her name says what she is — a mime, who copies what she is shown and can pull a solid copy out of the air; a question for Ken, not a build.

I think we should move away from including subsequent puzzles in each puzzle file — a server can fetch them and an artifact user can load them once into browser storage (if you rather we can postpone this). Yes I’d like to see your new Mimi. The ship shouldn’t be on the desk but in the background, big enough for Marty to travel in. I heard “hand it to the robot instead” while building the box of 8, 16 and 32. Picking up a rotated number rotates it again, and a cube’s face can end up not parallel to the desk. For the 1024 puzzle ask for exactly 1024 — then the user will need to stop the robot in time.

One file is one puzzle now, and the page carries the whole set by name — seven puzzles in five kilobytes of gzip; the drop-and-cache for artifacts is postponed at Ken’s word. Mimi is rendered: a mime, beret and stripes and white gloves up in the invisible-wall pose, Marty’s eye in her colours — a picture for Ken, not yet in the app. A world file has scenery: things that stand in the room, and Marty’s ship lies on the floor beyond the table at seven times hand size with its sign scaled back down. Puzzle 7 asks for exactly 1,024 from a single 1 and a robot that doubles: Stop — and now the full-stop key, which did nothing during a run — lets the robot finish the round it is in, so the moment is while the box says 512, and Marty says so; too late is 2,048 and Start over. A turned number keeps its turn when picked up; a number set down snaps square; and the desk with no robot at it is more table.

please add more puzzles … can you write a document describing how a user could create new puzzles — I noted that Dusty doesn’t seem to be able to remove stacks

Seven more, after the originals’ next steps and made of what is here: a box inside a box inside a box; three zeros in the second hole of a box; six zeros from a box of two, copies joined side by side; the door code 77 from a box of powers of two; a half from a 2 with a divide badge; a million from a 10 and a times-ten copied five times; and A, B and C on pads — the first that lets you type. Two things the new puzzles turned up: an “empty box” had always been a two-hole box, because the sparse form was never read, and the test hook that clicks a thing carried no point, so scripted drops stacked instead of adding. The recipe for making a puzzle is a document in the puzzles folder — the file’s shape, building one inside the workshop, the Python route, what the judge can decide, chaining and embedding, a checklist. And the hole in the workshop route is closed: Dusty swallows a stack, the rule goes with the save, a cube of it rides on his head, and a click gives it back.

If the user clicks on Next puzzle then stop any ongoing narration. I think the broken spaceship can look more broken. In free play I didn’t see the new Mimi — your design looks good.

Mimi stands at her machine now: beside the copier on the bench side and a step behind, turned to her platform, hands up — part of the copier’s node, so a puzzle without Mimi hides her with it, and the artifact builds carry her. Next puzzle, Start over and a robot’s load step all silence whatever Marty is reading out. And the ship came down hard: nose bent and scorched, a gash along the side, dents, one fin snapped off and lying behind, the stripe torn, the porthole cracked, bits scattered where it slid, and smoke still rising.

For the 1024 puzzle Marty starts off saying too much about how to solve it. Also why do we need a box (original ToonTalk did but we don’t). After using Ruby to erase the advice to erase came too late — no need to say it if it has already been done. The box in a box in a box puzzle shouldn’t have 1-hole boxes because they aren’t usefully nested. 2-hole boxes are better.

The box was never needed: a robot can set a thing down on its own desk where its given thing was, so the doubler is trained on a bare 1 — take, set on Mimi, take the copy, put it on the desk, take the original, drop it on the copy — and puzzle 7 hands out a 1 and a robot and nothing else. Marty’s intro is the need and the one fact that matters, and the recipe lives in the hints. The Ruby advice is said only while there is a red part left to loosen. And a box in a box in a box is made of two-hole boxes, each in the first hole of the next.

Can Mimi move and use her arms so it is clear she is running the copier?

She can. Her loose parts are regrouped at load under two shoulder pivots and a neck, and the copier’s own three steps — the scan, the copy growing out of the air, the copy lowered into the tray — each set her pose as they run, so she keeps time with the machine at any speed: she reaches up to the thing on the platform and follows the scanning bar down with her hands, gathers the copy between her gloves, lowers it to the tray, and goes back to her invisible wall, which she feels along, one hand and then the other, between copies.

The animation is ok when Mimi is given something but she should move her arms when taking something off the copier.

Whatever leaves her platform or her tray — taken by a hand, a robot’s claw or Dusty — Mimi hands over: from the tray her hands go down to it and open outward, from the platform they reach up and open the same way, with a look to match. It is an act of her own, so it runs whoever did the taking.

puzzle 9 has the boxes overlapping. when I joined 2 [0 | 0] one of the numbers became the wrong size

The table laid its materials a fixed distance apart whatever their width; it lays them out by width now, with a gap, so puzzle 9’s zero, three-hole box and two-hole box stand clear of one another. The wrong-sized zero could not be reproduced: joining two boxes of two zeros three ways gave four zeros at the four-hole size every time; the picture’s zero stands a little high, as a number does while it rests on another before merging, so the exact steps have been asked for.

When I dropped [0 | 0] on a copy I was holding it over one of the zeros (see tooltip) — I suspect that is relevant. After fixing this do some puzzles.

It was relevant: the zero under the pointer wiggles, and the wiggle writes back the size it remembers — the two-hole size — over the four-hole fit the join gave it. Reproduced with real pointer events (the hooks skip the pointer, which is why it would not show), and fixed where a thing is fitted to a hole. Then five more puzzles: the seconds in a year from three times-badges; ToonTalk from two pads joined at the edge; three quarters from a divide and a times; ¾ against ⅔ on a scale, bigger on the left; and a box of exactly 24 zeros by copying and joining three times.

Puzzle 19 gives too big a hint before the player starts. Make sure other puzzles also don’t start with too big a hint. Joining boxes doesn’t accept a drop like in the screenshot — any overlap between the left or right edge of what is held with the opposite edge of the thing underneath should be good for joining. True for pads too. Otherwise all the puzzles are good — keep going creating puzzles — especially robot training puzzles.

Marty’s first words now say what is wanted and what is on the table; the method lives in the hints, in six puzzles that had been giving it away. A held box or pad set down with its edge over the opposite edge of one already there joins it on that side, both ways, boxes and pads. And three robot puzzles: turn [3|2|1|_] round with a spare hole; count the letters on a nest, sending each on by bird, adding a copy of a one each round until the nest is empty; and grow a box of zeros one hole a round from a seed box, stopping it at nine — each trained and run by script.

the drops works fine but the tooltip isn’t correct — and the box underneath should wiggle when a drop is permitted. I think a new puzzle between 20 and 21 could start with the robot from puzzle 20 and different numbers. I am a bit worried about how a player might just move the numbers without the robot. Maybe the numbers are stuck into the box except the robot is stronger? puzzle 21 can’t use the bird in the 4th hole. the robot froze while picking up a copy of the box from the copier.

The bench now says what the drop would do and wiggles the box or pad that would be joined; the suite caught the same change joining behaviour pads to their neighbours, so gadgets and named pads are excluded. Things can be stuck: your fingers cannot shift them, a robot’s claw can — Ken’s own answer to why train a robot at all, and the numbers in the robot puzzles are stuck now. Puzzle 21 hands you the robot from 20, already trained and too fussy, so Ruby is the whole job; both puzzles move the numbers across into a second box, because a swap inside one box reverses for ever once loosened. The counter uses Dusty rather than a bird that has to fly home. And clicking the copier’s tray while Mimi is still scanning no longer takes the original back: it says the copy is on its way.

can you please generate an up-to-date version of making-of.html — add a section about adding media (and some generic enhancements that came up since the start of adding media). when it comes to the statistics can you split them into the release without any media support, the increment since then, and the totals. Include some new statistics about the number of exchanges we’ve had and the number of tool calls you’ve done.

The making-of now opens with a three-column table — the release before media, the increment since, the totals — counted from the git log and from the conversation’s own transcript: 154 commits and 217 prompts before, 41 and 126 since, 13,193 tool calls in all. Two new sections follow: what media asked for and paid back (a pad that carries a scene, look as data, a key press as mail, behaviours you can pick up, two hands, Dusty’s bag), and the two things nobody planned — a helper with a brain who writes down models and turtle steps, and the puzzle game.

The Making Puzzles doc says “Not behaviour… cannot be judged by a thought bubble” — true there is no direct “not behavior” but a robot behind can be arranged to run when the match is not something. Also put in your memory that American spelling is preferred even though I live in the UK.

Half the truth, corrected: a team is tried in order, so a member placed behind the others runs precisely when none of them matched — the only way to say “not” here, and what the judge has been using since the first puzzle to send wrong answers back with a note. A robot back there can count the tries or answer differently each time. What stays true is that a thought cannot name “keeps getting bigger”, so a puzzle whose answer is a process is written to leave a thing behind. And American spelling from here on.

The card repeated several times that Ruby erased enough … but it needed more erasures. For the puzzle with 10 zeroes I meant to make the robot drop a box in a box hole but it joined instead — Undo restored the box but the box I dropped wasn’t restored. Mimi blocks the view of the stack of boxes. After Ruby erased the 0 it should turn red since that wasn’t enough. A bad tooltip. The nest and bird are placed where a large goal blocks them. Marty’s broken ship should be further back.

Rebuilding a thought threw its red marks away, so an erasure that was not enough looked like one that was: the parts that still do not fit are marked again after every erasure, and the card says so — as an attention message, since a plain one cannot displace the refusal already on the card. Undo now puts back what the robot’s claw was holding, which is why the box he dropped had vanished. Tooltips only offer what the puzzle allows: no typing where the keyboard is gone, and the goal says it is the goal. Mimi and her machine moved off the stacks, the bird and nest are placed clear of however wide the goal is, and the ship lies further back.

Maybe puzzle 24 should introduce the idea of using a scale so that the robot like puzzle 23 can make a box with any number of zeros. And let’s add more. When I use Ruby multiple times quickly the narration falls behind and explains the old actions — no need to explain things that were more than one action ago — but the transition should be natural. Puzzle 22 has the nest obscuring the goal and the goal is tinier than need be.

Puzzle 24 gives the grower a scale: a count in one pan, the 7 wanted in the other, and a thought that remembers the scale tipping right — Ruby now keeps a scale’s tilt when she loosens what is in a pan, which is the whole use of a scale in a thought. The robot ran five rounds and stopped by itself with the pans balanced. The voice keeps at most one sentence waiting: a new message replaces what was waiting, never what is being said. And small goals stand half again as large, with the bird and nest placed where they hide nothing.

While training a robot Dusty wouldn’t vacuum the top of a nest stack — I had to move it to a spare work area and then vacuum it. Did you address the obsolete narration issue? Many more puzzles please.

In a lesson Dusty now takes the top of a pile on the robot’s own nest, addressed the way a take is. A saved thought keeps a scale’s tilt both ways. And eight more puzzles: 1,024 hands off, by a doubler weighed against a thousand; the biggest of three and a pair in order, with a scale by hand; a robot that swaps a scale’s stuck pans in one run; letters poured into a word, a word poured into letters, and the third letter of Marty picked out by a 3; and a halver that weighs itself against 1 and stops. The narration was fixed the round before: one sentence waits at most.

While training the robot I accidentally picked up the 1 instead of the box with the 1 in the second hole. When I tried to drop back in it ended up on the desk.

The empty pan hides under the scale’s wire, so the click meant the scale: the robot recorded “put it in hole 3”, the number was refused and landed on the bench. A drop aimed at a scale now means the pan on the pointer’s side, for hand and claw alike; an occupied pan takes the drop onto what is in it, and the tooltip says which pan.

The robot ran 1+6 times for the 7 zeroes puzzle but the narrator said “Ran 5×”. Puzzle 26 would be much better with fractions or very large numbers. Puzzle 28 has no motivation for a robot rather than the scale; I thought after 28 there would be a sorting challenge. Can we add a “smart camera” that zooms in and follows the action, with a toggle? Puzzle 32 is too easy to cheat by grabbing the 1 — and a robot strong enough to move stuck things could pull the 1 out for the player.

The 5 was an early start: after a lesson rewinds the thought still fits, and Ruby’s first loosening set the robot off; now an erasure runs the robot only when it turns a mismatch into a match. Puzzle 26 weighs fractions; 28 is framed as the smallest piece of sorting; 33 is the sorting challenge — four robots, a swapper and three movers keyed on which hole is full, sorting three stuck fractions and stopping by themselves (the first design’s spare hole added two fractions together, caught by running it). A claw moves a stuck thing only inside what the robot was given, so puzzle 32’s 64 and 1 are stuck and the balanced box is the answer — and a lesson’s rewind no longer forgets fixed and stuck, which it had since they existed. And a smart camera: with Ruby or Dusty awake, pointing at the thought bubble brings the camera in; a toggle in the More menu.

The balance question was an example of whether the scale should “know” that multiplying by 2 is identical to dividing by 1/2. There is some pedagogic value to this.

A number now weighs what it does: a divide badge folds into multiply by the reciprocal and a subtract badge into add the negative, so ×2 balances ÷½ and +3 balances −(−3), while an operation against a plain number leaves the beam undecided.

Some puzzles like 26 should not show the answer — a sign saying we need the biggest number would be more challenging; 27 should be like that, and harder. The smart camera should do more, e.g. when the numbers on the scale the robot manipulates are tiny. Puzzle 30 should hint how to make a 0-hole box. The Ruby tips are repeated too many times. The robots are making it hard to see the goal box. 33 is too complex for the first puzzle involving teams.

Puzzles 26 and 27 show a sign, not the answer, and 27 weighs fractions. In a lesson or a run the camera comes in on what the robot works on, and leans back out when you point at the side of the screen. Puzzle 30 offers the box stack and says how a box gets no holes. The Ruby advice is said in full twice, then in a few words. The sorting puzzle’s robots stand at the back, and it is puzzle 34 now: puzzle 33 is two robots, one run — a swapper and a mover that together leave the smaller fraction in the pan and move the bigger out.

Can we improve the way thought bubbles look? Both when a robot is inside and afterwards? More cloudlike maybe? Less circular and more textured? The smart camera does a good job when beginning to train a robot but it shouldn’t turn off user camera controls (e.g. zooming out if desired).

The thought’s halo is a cloud of soft sprite puffs with the thought showing through, and the lesson’s dome wears a tiled cloud texture, so both read as clouds rather than spheres. The smart camera leaves the orbit controls on: orbit or zoom and it lets go where it is, until the next lesson, run or thought you point at.

Better smart camera, but let’s not have it do anything while a user is moving the mouse — wait a second or two after the mouse stops. ChatGPT’s review: the clouds read as luminous fog and the thought is faint and small; the camera change deserves a regression test across a run, and the yield resets on transient gaps; program descriptions are inserted as HTML; the dev server’s path check is a prefix test; disposing one robot can dispose every cloud’s texture; the cloud tile’s wrap offsets cancel; a failed model load leaves “Loading…” forever.

The camera does nothing while the mouse moves and acts a second and a half after it rests; the player’s orbit holds for the whole occasion, checked by a suite run through a complete team run. Firmer, sparser puffs and a larger thought inside. Descriptions and saved names go into the page as text, the server judges containment by relation, the cloud textures are shared, the tile has no seam, and a model that fails to load says so.

Remember that after leaving training to pull the camera back enough to see the thought bubble. And when red parts appear in the thought bubble.

Both occasions now glide the camera back to a view that holds the robot and its thought, and leave it there.

It says the robot stopped after 17 rounds when it should be 18 (plus 1 before using Ruby). When the narration or Marty refers to anything — Ruby, Mimi, the stack of pads — the camera should pull back enough for that thing to be visible. You should always be able to see the work area of the robot, unless the user moves the camera elsewhere. Puzzle 33 can be accomplished by one robot — no need for a team.

The stop and run messages give the rounds in all with the thing on the stand when that differs from the rounds since Run. A message naming a helper, a stack, the notebook, the judge or the work area pulls the camera back until it is on screen; every smart pose keeps the robot’s work area in view; a glide under way finishes even while the mouse moves. Puzzle 33’s two boxes tip opposite ways, so two thoughts are needed.

One of the untrained robots in puzzle 34 is blocking the view of the scale the robot is working on. I picked up a team and typed Ctrl+C and it said copied but nothing was on the clipboard. 34 is tricky and if you make a mistake you have to start over — there should be stacks of untrained robots, training boxes and test boxes. A scale with an empty pan should lean towards the pan with something in it.

Ctrl+C with a robot or team in hand copies it as text and Ctrl+V with an empty hand takes it back. Puzzle 34’s spare robots are gone: the stack of little robots and Mimi supply robots and practice copies, and Mimi’s copies keep stuck things stuck. A scale with one full pan leans toward it.

When Ruby is activated pan and zoom into the thought bubble. If the erasures mean that the robot matches and will run then the camera should zoom out to watch the robot run.

Waking Ruby or Dusty brings the camera in on the thought; an erasure that makes the thought fit sends the robot off and the camera out to watch the run, resting there until it ends.

I’m about to introduce ToonTalk 3D to my grandchildren, starting with how to move the camera; then Marty can take over. But what about visitors with nobody to explain? Should Marty explain the camera, depending on mouse or touch — for new user names, a button, or part of his greeting? And Marty should occasionally use the user’s name when it seems natural.

All three: a first-time name is welcomed with the offer, the greeting carries it, and a Look around button stays in Marty’s panel. The lesson is a demonstration — Marty turns, zooms and slides the camera himself, in mouse or finger words, and hands it back. He says the visitor’s name where a person would: the greeting, the welcome, the end of the lesson, a solved puzzle.

The app won’t load — it shows “Could not load robot_v4.glb — Maximum call stack size exceeded.” I think maybe the notebook has a very large object in it. But I don’t get to see how to enter the user name.

A notebook page that cannot be built now shows a note in its place, a notebook that cannot be restored is parked under a rescue name, and ?fresh on the address ignores stored state for one visit without touching it.

My grandson wanted to make a town/village like in original ToonTalk. We tried to have a robot make lots of houses but that didn’t work well: lots of platforms appeared but most were empty, and some intersected the stacks. Marty and narration repeated some instructions. At some point I couldn’t navigate any more; no navigation when the desk is being enlarged. My granddaughter asked Marty by voice to make something and was told “Use **Make** and ask Marty” — notice the markdown. We need to brainstorm how to make a scene with 3D models.

Measured: every copy after the first went inside the first house, because “set it down on spot 1” met a house on spot 1 and a drop on a house means inside. A drop on an empty spot now remembers the spot was empty and a taken spot means the next free one; drops onto things still combine, so saved programs keep their meaning. The spots are laid out clear of the stacks. Reshaping the table keeps the camera, and only a corner in hand pins it. Marty says a line once, strips markdown, speaks as himself, and “make me a lion” in Ask or by voice is Make. The scene is a design, brainstormed and not yet built.

How about a door inside a house to a room for making scenes — model world, scene maker, microworld? Should users be able to edit a door’s label, and the door back have a proper one? My grandson asked what the crashed rocket was. Go ahead with all of these; yard is the best name. And on touch, my grandson didn’t realize he was still holding something, and moving his finger over it rotated the camera.

A back door beside the tall one leads to the yard: the table stays indoors and open ground takes its place, with your hand, the stacks, the robot and Mimi along — so a robot’s copies and Marty’s toys land on the grass. The yard’s things wait while you are inside, save with the world, and fold into a house with the house. Doors wear signs saying where they lead, and typing while pointing at a door names it. A finger on the held thing drags it. The rocket stands where it landed, leaning on a bent fin.

Ways to populate a yard: carry out a box of items and leave with the empty box; put a nest in the yard, give items to the bird, arrange the pile and leave with the nest. A robot should be able to do these too. Make a sample zoo in a yard. “I want another unicorn” should have been Make. No need for Ruby in the yard; a way to hide Dusty and Mimi and bring them back. The user should be able to move and resize the door, perhaps by its frame.

Outside, a robot’s drop on the grass is a step of its own — “set it down on the ground” — and a run finds a free patch each time; the box and nest ways need nothing new. A wish without the verb goes to Make. Dusty, Mimi and Ruby each have a switch in the more-menu, and Ruby stays indoors in the yard. A door picked up by its frame follows the pointer; the arrows turn it, + and − resize it. The zoo lives in examples/yard-zoo.world.json.

Not an appropriate tooltip for Dusty. Go ahead with the open yard issues. The yard was working and now I don’t see its door. Add Marty to the menu; maybe a general way to remove anything from the workspace, even stacks. “Dusty: put away” should read differently indoors. Dusty removing labels didn’t work on a 3D model, the whole model was vacuumed. + should permit larger sizes. Holding a pad, up and down should tilt it, so a background image can be put up in the yard. When asking for a drawing, use text-to-image if the LLM supports it.

The back door is a tool now, hidden only by a puzzle’s rules or by choice; it used to hide in every puzzle. “What is here” in the more-menu ticks Marty, the helpers, the back door and each stack in or out. Dusty takes a name off and leaves the thing. A pad tilts fifteen degrees a press and stands where it is set. Doors go to six times their size. Draw paints with OpenAI or Gemini and keeps the turtle elsewhere. The yard grows at its edges and keeps its size; Marty knows when you are outside.

Clicking What is Here closed the menu. A door moved in the yard ended up far away in free play — door positions should be per place. Other objects, models and pads, should have a much larger maximum size. Dusty doesn’t move to remove a label. Typing on a held 3D model should edit its label. Saved worlds should be named for yard or workshop. Why did I hear the tilt line twice? Hiding and showing should be per place. A robot should be able to go to the yard holding what it has; clicking the door while training said to wait.

Doors and the What-is-here list belong to the place you are in, remembered and saved for each. A robot shown the back door goes out with its load and comes back in, and the run follows. The menu stays open; models and pads grow to twelve times; Dusty flies over for a name; a held model is named by typing; the file is yard.world.json from the yard; the tilt line is said in full once a hold.

The camera doesn’t follow a robot placing things in the yard. I moved the door in the workshop, loaded a saved world, and it went back; in the yard it was at the default place. Objects a robot places in the yard overlap — they should only go where there is room. Marty, Dusty and Mimi should stand behind the yard, as they do in the workshop.

Outside, the smart camera follows what the claw carries instead of holding the desk in view. A free spot is measured at the size a thing is shown, with rings sized to it. The ground begins past the helpers, who stand between the stacks and the grass. A world file carries door positions only once a door has been moved; each place keeps its own doors.

A user should be able to make a pad as large as the yard, for a different kind of ground. Is the show/hide setting saved with a world? It should be. The reshape table button should say reshape yard in the yard. After a robot places something in the yard as the last step of training, it should walk back to work, not jump.

“As big as the ground” on the holding card sizes a pad to the yard or the table and lays it over it. A saved world carries what is put away, indoors and out. Reshape yard: the handles stretch the yard, the near edge fixed. The robot walks home after a lesson.

Go ahead with the wandering behaviours for animals.

A sixteenth gadget: each round a die of three, a −2 and a ×1/25 land on each step in turn and a copy goes to the bird, so a thing drifts nowhere in particular. It has its own world, a place on the shelf, and a copy on the zoo's grass to drop on an animal.

Go ahead with the contagion rule and the manual update. Happy to experiment with the drop preview and decide whether to keep it. I like a setting that lifts Marty’s restriction on creating programs, with the current setting as the default. Consistent wording is important — any problems doing so for a wide range of ages?

The root keeps the approximation mark, with a check across every operation. Drop hints: the tooltip’s first line says what letting go will do, switchable in the menu. How far Marty goes: hints and demonstrations (default) or planning programs step by step, per person. The manual’s two contradictions are gone, its history moved to BACKS, and it opens with a first project the suite replays.

Older learners and teachers won’t know how to get Marty to use computing words — a switch? In the wandering panel I didn’t see the bird fly away and return. Redo wandering with the turtle commands. Add a Marty option for high-level commentary while a robot works, like good comments; and when a user asks about a robot, house or panel, held or by name, Marty should suggest running it with commentary. The current answer was inadequate.

A Words switch pairs each workshop word with the programmer’s word. Marty is told a work box hole by hole and each step’s target, so purpose follows. A question about a thing that runs finds it and offers a run-with-commentary button; commentary, a tick box, speaks purpose at a run’s start, its stop and a switch-on. A drop on the bird is a flight in the panel’s mime. Wandering sends yaw and forward, so an animal faces where it goes.

Go ahead and make all those changes. Regarding the infinity exercises, have you seen toontalk.com’s Infinity documentation and its links, including the teacher guidance and the worksheets?

Read the worksheets; two of Astra’s points are in Ken’s own teacher notes and the edits echo them. Zeno gained a gap-finding challenge and keeps partial sums apart from the limit; Activity 3 sets 5, 5, 5… against 1, 2, 3…; Activity 4 says covering, not one-to-one; Activity 6’s nest is a claim to investigate and says why 1 is missing; Activity 7 argues from reversibility. Melody, the airplane and wandering put experiments first, the airplane asks whether its loop is a circle, the ship repairs across the puzzles, and Zeno and Melody are trained by demonstration in the suite.

Should the “room stack” tick and tooltip say houses, since that’s what they look like? When training a robot to obtain a panel it says to leave the thought bubble first — why can’t the panel float to the robot’s work area? I want a robot that gives an object a behaviour by obtaining the panel and adding it to another panel. A 3D object in a box looks like its label; zoomed and rotated, nothing appears in the hole.

The house stack. In a lesson, ⚙ with a thing in the claw takes its panel out onto a work spot, and a panel dropped on a panel nests whole — a robot can give a thing a behaviour that way, measured. A model in a hole was covered by its own readable name plate; it shows itself now.

Crocodile in hole still not fixed. I still couldn’t train a robot to put a behaviour on the crocodile: I obtained both panels, but when I picked one up I couldn’t put it back or onto another platform, and when I dropped the panel in a box hole it disappeared. I couldn’t drop a panel in a box hole even when not training.

A model in a hole rests on the rim now, where the pocket wall no longer hides it. The panel dropped on the crocodile in its hole did bind the behaviour — the tray then flew to the bench, out of the lesson’s view; in a lesson or a run it lands on a work spot. A panel dropped in an empty hole is refused in so many words, without ending the lesson; by hand, a panel dropped on a thing in a hole binds. Found on the way: a pad dropped on its own open panel nested inside itself.

After picking up the crocodile’s panel I couldn’t set it down on a work area. A fresh 2-hole box, typed 3: it worked but the narration said 2 holes. Dropping the wandering panel on the crocodile’s panel worked but it is displaced to the side. I’m training but the “run what it learned” button shows instead of stop training — I think because I clicked the gold knob to return the panel to the crocodile. The saved robot doesn’t have the knob click or the rest.

One cause for three: binding a behaviour rebuilt its panel by stashing the outer world’s mode and hands — one half of a push — which ended the lesson silently, so the knob and later steps were never recorded and the panel afterwards was in your own hand. Fixed; the stale second world root that showed a stray robot went with it. The knob is a step now (“put away the panel on spot N”), a panel’s contents are centred on its floor, and the box words say the count typed.

I can’t go back inside after entering a panel while in the yard. And I think I was wrong about Ruby: since you can train a robot while in the yard, it should say “Ruby (inside only)”.

The exit door was hidden whenever the yard was open, so a panel entered from the grass had no way out; only the yard itself is without one now, and the sign reads “Back to the yard”. Ruby comes out to the yard, listed as plain “Ruby”.

Let’s postpone the broker house. Please add the three enrichments. The anima-gadgets of original ToonTalk were much easier to see: how can we make a Space Invaders game whose panel reads as a collection of gadgets, each easy to inspect as in the photos? Try to make one and see how inspectable you can make it.

The touch reading says who by name and which way; a scene answers touches with every pair that meets; things can be shown, vanish, or drop a working copy beside themselves. Space Invaders is built from those: each picture’s back is a page of sentence cards, magnified to read; the gear over a card opens its own back beside, robot and box at toy scale; Enter frames each; the knob folds them home. A panel dropped on a panel now goes in as its card. Found on the way: a hang when a dozing robot’s box held an open panel.

Let’s organize the examples at the top level of the examples folder into existing or new subfolders. Pong, airplane, and maybe others in behaviours should move. Add emojis when appropriate to all the examples’ filenames.

One folder per subject — numbers, lists, words, accounts, yard, games, models, infinity, behaviours, sounds, images, devices, puzzles — and an emoji before every world’s name. The Pongs went to games, the airplane’s flight to models, Zeno to infinity. Every generator, the suite, the goldens, the activity sheets and the manual follow the new names, and all forty-six generators rebuild their worlds byte for byte. Found on the way: a working panel dropped on a panel rides inside it again, so folding the group keeps it alive.

On the explode card’s back the tiny robot is dancing while the other looks too big; a waiting team should differ less in size. The bird may be a bit big, and the door enters the frame. In a closeup of a panel, extracting a sub-panel should show it in closeup too; entering and leaving closeup while inspecting is awkward. Enter while holding should also switch to closeup.

The round’s mime moved the leader parked in the queue instead of the member performing at the desk; it moves the performer now, and a team standing by is half-size rather than a ninth. The bird is smaller and the door stands inside the rail. Closeups nest: the gear takes a closeup into a card’s panel and the knob or Escape comes back to the panel it stands on; Enter works with something in hand, and Shift+Enter is the new line.

The regression check “the camera shows the thought” fails headless, and failed the same way against the app from before the last two days’ changes: find why the red view no longer reports on screen, whether the app or the check drifted, and fix whichever is wrong. Zeno’s postman takes more than twenty minutes on its own — should the check pull both levers earlier, or the world cap the pile?

The app: a refusal marks red parts and in the same breath names Ruby, and the mention’s fit of the table and Ruby replaced the thought view — the thought stood above the top of the screen. Its earlier passes were order luck, a preceding check having left Ruby already in view. A mention now keeps a view already asked for, or fits the thought, the work area and the named thing together. Zeno: at Instant every frame is eighty halver rounds and the total grows to tens of thousands of digits; the check pulls both levers first and reads the invariant off the first eight deliveries — seconds instead of twenty minutes. The world stays uncapped: a dropped letter would break the exactness it teaches.

In the Pong gadgets world, moving the paddle shows a tiny bird or two flying across the table with no clear start or end. Add a way in the trained actions area to write a comment on a robot that is persistent; all the examples should have comments like this, and the trained actions should display the steps and comment of any robot held by the user. Testing the sentence generator shows two thought bubbles where only one should be shown.

The bat’s follower worked in a hidden tray in the middle of the table, and every round it performed set a bird flying from there; a panel out of sight performs nothing now. A team’s standby members no longer wear bubbles at the desk: the performer’s thought is the one on show, the rest read on the card. The card has a note under the robot’s thought, saved with the robot wherever it goes and read by Marty; the card shows the steps and note of the robot in your hand, a member at a time; and every example robot carries a note, written into the generators.

“Run what it learned” is right after training; otherwise the button should say something like “start the robot”. A robot taken out of the grammar team became huge; hovering over team members shrinks them before they are clicked; a second member picked up ended up a normal size on the desk. Robot tooltips should include the comment. Space Invaders taken to the yard and made as big as the yard did not scale its game elements; it is hard to drop it so it covers the yard, and it wiggles under the mouse.

A loaded robot’s button says “Start the robot”; only a robot you have just taught offers “Run what it learned”. The three sizes were one cause, a stale mini flag: a team at the desk now stands whoever is performing, the hover wiggle keeps a standby at doll size, and a member taken out is a little robot again with its thought over it. Tooltips carry the note. A field with riders is fitted to the yard by size, so the ship and invaders come with it; a ground-sized pad lands centred and does not wiggle.

Testing Marty’s commentary with a robot that gives the wandering behaviour to a crocodile: if the user wants narration the robot’s speed should be ignored and match the narration instead. When the crocodile ran it did wander but the app became very slow; the speed menu stayed blank for seconds.

A run with commentary now starts when Marty’s opening line is on the card and spoken. The slowness was a ticker folded inside a thing: the inner search that lets a house revisit its own houses freely gave a nested panel fifty rounds a turn, a hundred a frame — 690 ms a frame, measured. A nested panel now gets one turn per parent turn, like every ticker: 24 ms a frame, and the crocodile still wanders.

Marty’s commentary should cover every step of the robot’s actions, and the robot should wait until he has finished describing a step. The user should be able to pick up, move, resize, vacuum or take to the yard their notebook. A third help mode could have Marty help plan and create programs, engaging the user with questions while ensuring progress. “Write programs” is not a good word. The arrow keys did not work for Space Invaders at full size in the yard.

A round with commentary on says one line per step and holds the robot until it is heard, at any speed. The notebook is a thing you can carry, place, resize and vacuum, and it remembers its place and size. A third help setting makes Marty a partner: one question at a time, the plan checked, one move handed over at a time, and a step done for you when you are stuck. Nobody writes programs here — “build”. The keyboard nest ignored keys while the Speed menu held the focus; only a text field keeps a key now.

Implement robots that train robots the way ToonTalk Reborn did — a robot gives an untrained robot a box and then trains it, without extending the API — with text-to-speech for the meta robot, perhaps as a general capability of pads; then make a simple example of a robot trained to train robots.

In a lesson, the claw dropping a box on a little robot is the step “teach”: the pupil steps up to a desk of its own, what is done next is its lesson (mirrored into the teacher as taught steps, Ruby’s loosening included), and “Stop teaching it” ends it. Leaving the bubble un-teaches a pupil taught in the dream. Run, the teacher teaches for real and the pupil stands trained at its desk. Pads speak: the Read button, a “read aloud” step in a lesson, or [speak] to a pad’s bird. The example is 🎓 teacher in examples/meta.

Running the teacher: the pad’s words were heard twice; the pupil is tiny with a full-size arm, then lying down; the pupil takes a 1 from the stack where it should use the number the teacher provided; stopping the pupil, the narration invented a reason; commentary should only apply at 1x.

The pupil kept the flat toy pose of a robot in a box hole; it stands up as it steps out. The card no longer reads aloud what the pad’s own voice says. The pupil’s box is a count and a 1, and it counts with that 1. The closing commentary is given the workshop’s own account of the stop and told never to guess another. Commentary keeps to 1x.

The camera moves to show Dusty when running the teacher robot. After the pupil’s training is finished it faces the wrong way in an impossible location, colliding with a platform. Marty says “I’m trying to make the count become 1” and then switches to “It” — if he is reading a comment he should say so, or was there another cause?

A line naming a helper moves the camera to it, and Marty’s own commentary names Ruby mid-run — so the view left the working robot for the helpers’ corner. While a run is on, the run’s view owns the camera. The pupil’s desk aside stood inside a work spot’s platform, and the pupil was left wherever its last step took it: a slot is now taken only if it clears the spots, stacks and desks, and the pupil walks to its own desk and squares up. The “I’m” was the model slipping into the robot’s voice; both asks now pin Marty as the watcher, the robot as “it”, and a note as its author’s words.

When I give the box to the teacher Marty correctly reads his opening line but that causes a very long pause before the first action — I think they should overlap. After the pupil has run a cycle it says “changing the 0 into 1” — but the 0 is no longer a zero. I wonder when a robot is working if the auto camera should move higher, not directly above but a good deal higher so it is easier to see what is in its boxes. And when I changed the speed from 1x I still hear the commentary.

A narrated run made two asks of the brain in series and then read the whole opening out before the first step: three waits with the robot standing still. Both asks now go at once, the robot sets off, and the opening is read while it works — a line he cannot say at that moment is not said at all rather than queued behind. His lines for the steps are said again on every round, so the ask forbids naming any value a hole holds — the lesson’s numbers as well as this round’s. The follow, level with the bench at twenty-four degrees, is tipped to forty while a robot runs, which opens the boxes on the desk to view. And commentary keeps to 1× and ½×: speeding a run up mid-way ends it, his line in the air with it.

The camera didn’t follow the use of Ruby after training the teacher robot. I wouldn’t say “replace” when talking about adding 1 to 0. When there is a team, saying “it” can be confusing — maybe refer by name if it has one. The camera angle could be greater and more zoomed in to watch how the factorial robots work: the box the robot is working on should be easier to see, while still maintaining the bigger context, but the left third of the view isn’t needed. And the nest is placed on top of the notebook in the factorial example.

A robot having Ruby loosen a pupil’s thought was not an occasion the camera answered, so the one moment of the run worth watching happened off the picture; it goes in close now and hands the camera back when she is done. The wide picture had three causes: a fixed distance whatever the screen’s width, a fit that held the desk in view while the robot worked two metres away, and the lean-out that fires whenever the pointer leaves the picture — which is what reading Marty’s card does. Measured on the factorial robots: five metres back became one metre seven, and the box grew from a fifth of the screen’s width to a third. Marty is now told what a drop does (a number on a number is arithmetic, never a replacement) and to name the member of a team he means. And the notebook steps aside when a world’s things land where it sits.

When a number cube has been rotated ensure that the text is rotated to be as easy to read as possible — e.g. the scientific notation face in the previous attachment. And: please generate an up-to-date version of the making-of page.

Turning a cube left the face you asked for upright and the other five wherever the turn put them: measured on a cube tipped one quarter, two faces upside down and two reading bottom-to-top up the side. Each pane is now rolled about its own normal to the quarter turn that reads best — up the screen for a pane seen side-on, away from the front of the table for one you look down on — so every face of a turned cube scores upright. The making-of page was rewritten for the whole project to date: twenty-one working days, 241 commits, and five new sections for the camera’s occasions, the yard, panels inside panels, teams and notes, and robots that teach robots.

Please add activity 8 from the Exploring Infinity page to the infinity folder. Do you have ideas about how we might make a variant of the Resort Infinity? Perhaps in the yard?

Activity 8 is Cantor’s diagonal, and it was the one the folder said could not be built: a robot says “hole 1 of what I was given”, never “the nth one”. It can be counted to instead, and the counter is a scale — tipped one way a robot skips a term and vacuums it, balanced it hands the term to the bird, tipped the other it takes the next sequence in. Three tilts, three robots, no counter anywhere else, and each dozes on exactly what it needs. Measured on the three rows it ships with: the diagonal reads 1, 3, 4, and the “Add 1 to it” room turns it into a sequence that is none of them. Hand a box to the bird before pulling its room’s lever — a term delivered while the bird is still carrying the box can be missed. Resort Infinity is sketched for the yard rather than built: a cottage is a house on the grass, an address is a place along the row, and the move robot’s answer is something every guest walks to.

Yes build the “infinity yard” and start with the first 2 problems. Let’s add the camera state to saved worlds. The making-of should provide the statistics split by when we first introduced images and other media (around 23 August) and since.

Resort Infinity is built, out in the yard: a cottage is a house on the grass, an address is a place along the row, and making room is the row shuffling up. The design was forced by one rule — a team stops at the first member waiting on an empty nest, so nobody may doze on two nests. Each guest and the clerk have ONE nest each, and what lands says who runs; a guest’s nest answers to its own name and the bell’s by alias, and the desk tells a new guest from a mover by the shape of the letter. Measured end to end: six house themselves at 1–6, the bell moves them to 6–11, and five newcomers take 1–5. The camera now saves with a world when the player has placed it themselves (the goldens stay byte-identical), and the making-of’s figures split at 25 August, the day a picture became a pad: thirty tool calls to the prompt before, fifty-four since.

When I vacuumed a page from a notebook it didn’t end up in Dusty’s bag. Activity 8 started to work but after it created 3 numbers in the diagonal nothing more happened. The nests are not placed well since they quickly obscure what is happening behind their stacks.

An open notebook draws a page number, its entry, the next page number and its entry, and keeps them in one list in that order — so counting into that list by the page’s number found the numeral for a left-hand page and the neighbour’s entry for a right-hand one. Dusty emptied the right page and pocketed a numeral. The entry is now found by what it is, and a check vacuums both pages and asks for them back. The diagonal stopping after three sequences is the activity rather than a fault — it has read every row it was given — but it said nothing, so the pad now does. And the watch nests, whose piles grow into a wall, have moved to the front corners where nothing stands behind them.

I like the emoji in “press the microphone 🎤 and speak…” but it causes the narration to say “microphone microphone” and “speaker speaker” — maybe emojis should be removed before sending to text-to-speech? And: we should be able to import 3D models? Implement it for formats that make sense.

An emoji stands beside the word it illustrates, so a voice reading it says the word twice. Everything spoken now goes through one filter that takes out emoji — with their variation selectors, skin tones and joiners — and the workshop’s own icon glyphs, then closes the gaps; arrows and arithmetic signs stay, because “the ← and → arrows turn it” is a sentence about arrows. And a 3D model is now a thing you can hold: glTF is the format every character here is already made of, so a .glb dropped on the page arrives named after its file, sized to the table whatever units it was made in, standing on its feet — and it rides inside the saved world, which is what sets the nine-megabyte limit.

I downloaded the Khronos Duck’s glTF-Draco variant and when I imported it, the app said it couldn’t process it — only the label appeared. Is there a better version somewhere in that folder?

Yes: glTF-Binary/Duck.glb, one file, 120 KB, which comes in and stands on the table. But the refusal was the real fault, twice over: it said nothing useful, and it left the name plate standing over nothing. A model file is now looked at before it is believed, and four troubles are told apart because each has a different thing to do about it — squeezed with Draco or meshopt (no unpacker here, look for a plain .glb), only a table of contents (it names the files that did not come with it), a web page saved instead of the file (use the download button), and not a model at all. Nothing is made when a file cannot come in, so nothing is left behind.

A batch from Resort Infinity: the fence pad says eleven cottages in a row when they are in two; behaviours should have a comment field that tooltips include; importing a world with things in the yard should say so; a pad’s tooltip wants a line between what it is and the generic part; the workbench calls itself a workbench while I am in the yard; problem 1 never says how to get a box to train on; why does a pad tell me to train a robot when one is already trained; the camera switches away while a robot uses Mimi; and a bare sine pad shows 0 rather than its name, and would not follow the mouse.

One bug was behind three of those: the plane a carried thing slides along was measured once from the robot’s reach at the table, so out in the yard everything you picked up floated 1.09 m over the grass — drawn far from the pointer, which is why a pad appeared behind a cottage nobody carried it to. It now comes from the ground you are standing on, and the words follow it (grass, not workbench). Tooltips grew a rule between what THIS thing is and what its kind does; a behaviour can carry a note like a robot’s, which its tooltip says first; a sine pad wears the word “sine”, since sin and cos ignore the number they ride on; the camera keeps its eye on Mimi while she scans; opening a world says how many things are out in the yard; and SPACE with something in your hand now says where the key went instead of silently typing a space into a name.

I copied the airplane and pressed SPACE on “the pilot”. Only one copy flew — shouldn’t the copy have kept the bird connection so the gadget broadcast to both? And I typed “.” to the pilot and after a while it stopped: why the delay? Also, the label of the imported duck is in the wrong place, and there are no tooltips for 3D models.

The broadcast is real and is how the world already works — the pilot posts to an ordinary nest and the behaviour BOUND to each plane reads it, and an ordinary nest’s name is never renamed on copying, because sharing it is joining the flock. What was broken is moving a behaviour from one thing to another: it always refused, because the binding code asked what the GADGET’s own name was rather than the name of the thing it is bound to. Fixed and measured against the previous build. “.” rests the robots but not what they have already sent, and the message now says so. The duck’s name plate is measured onto whatever shape the model came as, and a model has a tooltip at last.

Build the yard panel with birds in the report — and filtering by name would be convenient. Make another airplane where the behaviours are all local to the object, so you can turn the airplane on and off. And the text pad and the box overlap in the screenshot: that can cause flicker and should be avoided in all the example programs.

The yard is a thing now: a node with a name and a panel of its own, opened from under What is here. [query | things | bird] answers with a bird to each thing on the grass, its name and its place — a word in the third hole filters — and [listen | things | bird] hears things arrive and leave. The airplane-with-pilot carries its turtle and its pilot inside its own panel, so SPACE flies it and “.” lands it. And every example world is measured by the suite for things standing on other things: twelve had real overlaps, most from the table clamping z at 2.19 so that two authored rows were one; all are re-laid, and the rule is written down.

Please add a yard panel example to the yard folder. Maybe add a button that queries the zoo yard and adds a wiggle behaviour to all the animals.

The zoo keeper: a brown pad by the zoo’s door whose robots write to the yard with [query | each | bird] — one letter per thing on the grass, ending with its kind — and give each entry whose kind is “model” a wiggle by mail, [bind | pad], one animal a round. Writing it turned up what the vocabulary lacked: a report delivered one thing at a time, so a robot can walk it; the kind of each thing, so the welcome sign is spared; and a behaviour given by mail, as dropping the pad on the animal would.

Some of the wiggle behaviours are blank. Wiggle the animals works but typing “.” doesn’t stop the behaviour. The elephant doesn’t wiggle. When I pick up any of the behaviours and type control-p the panel appears at the far edge of the yard in the center; there should be animation as it comes out (and when it returns via the knob). Same with the info notebook.

The face-painting drain discarded a pad with no parent as gone, and a behaviour taken out of a letter has none for a frame: kept now. A behaviour handed out by mail remembers its giver and is switched with it, so “.” on the keeper rests every wiggle and SPACE wakes them. The elephant turns three times a second like the others; sampled once a second that reads as still, and a screenshot catches each animal at either angle. On the grass a tray goes beside its thing, every way out grows from the thing and every fold shrinks into it, and the info notebook comes out of its plaque and goes back into it.

When I picked up the pad “the row goes on” and clicked to read it I heard it read twice, with unusual pauses. Each problem should have its own page. Problem 1 refers to a box to train on but the only box is the one with the nest in it. “The guests” and “five more guests” don’t do anything when I type space to them. The tooltip should include the box label. The switches on houses are hard to access — maybe on the front. Pointing to a house should say its name and how it can be turned on or off, and how it can be made opaque.

Read spoke the words and the hint reader spoke them again; a voice pauses at every hand-wrapped line break, so single breaks are spaces now and blank lines end sentences. Clicking a pad picks it up and SPACE on a held pad typed into its name: a behaviour in the hand is set down and switched instead. Problem 1 names the box, the training moves have a pad of their own, and each problem fits one tooltip. A box’s tip starts with its name; a house’s says its name, its walls, whether it runs and how to switch it; the lever stands on the front beside the door.

Activity 8 is confusing — screenshot 2 is what I see when I turn it on.

A tower of terms: the sequence rooms ran for ever and stacked their numbers on the boxes still waiting to be handed over. A sequence is made on demand now — a room dozes on an “asked” nest and answers each request with one term, and the diagonal team asks for the next term as it takes each one — so levers and boxes can go in any order and nothing piles up.

Infinity resort is working but I find it very confusing. Why are there 11 cottages and they disappear and reappear when the robot runs? Problem 1 moves cottages 2 to 6 and then cottage 1. Why? We need to convey the idea that guests at first move to a cottage 5 down so the new guests can have rooms. Moving houses is just confusing. The activity 8 layout is confusing, and is it supposed to stop after doing just 3 numbers?

The cottages stand in a fixed row of eleven now and the guests are pads that walk to the cottage they are given, and a thing told where to stand glides there instead of jumping. Guest 1 was housed last because the courier set her own letter down after the five that rode along; letters land in posting order now. Activity 8’s five rooms stand in one row with the boxes and pads in front, and yes, three rows given means three terms: it waits for a fourth.

We need a bird to the “computer”. Maybe the first example is to query a timer or the time; then using the number API construct something like the timer sensor. A “computer” notebook in the devices folder: page 1 a text pad, page 2 the bird, the rest alternating doc and sample messages. The door code and powers of 2 is good but it would be nice to have an additional one that involves a bigger number. Maybe the year?

The computer is a thing with a fixed name that answers [query | time | bird], [query | date | bird] and [query | clock | bird]; a number can be told [set | value | n]; the devices folder has the computer notebook and a timer built from one robot. Puzzle 35, played after the door code, asks for this year from powers of two, and its judge asks the computer what year it is.

Let’s start on the second arc of 3D puzzles.

Four puzzles after p34: the lion told where to stand, turned until its facing reads 0, given the walk, and carried out to the grass. Their judge asks the lion (or the yard) once you give its bird a pad saying done, and reads the answer off its post; a wrong answer comes back with the “not quite” pad and the done pad. A model’s facing reading now follows the turn it actually has.

When I dropped the timer panel on the number panel the timer pad began to float over the panel. Inside the timer panel the stop button didn’t work — it just started the next cycle. I typed “.” to the number but it didn’t stop. Can it show seconds instead of milliseconds? And: a user enters a panel with an untrained robot and trains it on the box dropped there, with the panel’s bird at hand; a response should appear while training; a second robot trained on the response joins the first as a team — a composable, transferable behaviour.

A card nested in a panel stood at table height and a panel has no table; it rests on the floor now. Stop inside a panel holds the auto-run and rests the room; “.” and SPACE on a thing switch the robots on its own panel. The computer answers [query | seconds | bird]. The timer is rebuilt as two robots on the number’s own panel taking turns by a pad crossing between two holes.

Having access to the “my thing” bird while training should work even when nested, since this bird goes to the object of the outermost panel. Let’s try it: just the my thing bird, available during training, and the robot will access that bird when run. A user should be able to test such a robot without entering a panel by placing any bird on that pedestal.

The perch: a pedestal beside the robot’s desk. On a panel it holds a bird to whatever the panel is the back of, resolved when a letter is given and on up through nesting and binding to the outermost thing; on the bench it takes any bird of your own. The timer’s second robot now gives its letter to the bird on the perch, and its box holds no bird to the number. Two meta worlds, telling and timer-teacher, show a robot teaching robots to do it. Every behaviour example now works the perch way: no bird to my thing in the box, a put on the perch instead.

The meta timer example doesn’t involve panels — it should end up with a number that when turned on is a stopwatch. When I tried to train a panel robot to copy a message, give it the thing bird, and then drop a 1 on the number in the box, the training started with the drop of the 1, and the copying and giving were not recorded.

A box and a fresh robot dropped on a thing’s panel are a lesson that begins as you enter; the copier and the perch are learned. The little robots a teacher taught stay among its things, so the timer teacher now takes a number’s panel out, sets Tell’s box, Ask and Tell on it and folds it away: the number is a stopwatch.

A copy of the stopwatch did nothing when started, with a stack of unprocessed responses inside. Turned off and set to zero, it resumed its old value on starting: could a thing announce when it is started? The pupil should be half size. A white circle comes and goes on a work spot. “Move up five” fails to match the five more guests’ letters, and the ding pads are confusing. Say “inside”, not “the back of a thing”.

A copy’s private posts are its own. A thing announces its switch ([listen | switch | bird]), and the stopwatch starts from whatever it shows — four robots, taught by the timer teacher, with Dusty on a pupil’s thought a taught step. Pupils stand half size once taught. The white circle was the perch, now a proper pedestal with its name. The resort’s clerk is a team and the bell an announcement. The two old suite failures were one glide fault, fixed.

The volume control slider doesn’t affect text-to-speech. The tooltip could be better given that the robots have names, and with no names “the robot” or “the robots” beats “it”; the little thought’s tooltip suits an empty hand, not one holding something. An empty hand on an empty box hole should pick the box up. Testing the resort, the clerk did nothing once when given the nest after starting the guests, and the old guests didn’t move five cottages over.

Every utterance is made at the slider’s volume. The drop-on-a-robot lines name the robots, say “they” for a team and “the robot(s)” for the nameless; the thought’s line asks for an empty hand. An empty hand or claw on an empty hole takes the box. The resort’s clerk goes to work on the drop of the desk, so “press Start” on the pad was a Stop; the pad says so now.

The infinity resort still shows the first guests being replaced by the next five — they don’t move first. Also let’s make the guests a simple model of a person; the two colors (maybe clothing) are a good idea.

A guest is a little person of solid shapes with a name plate, red shirts for the first six and blue for the newcomers. The moving-up is measured right in every order and speed tried; guest 6 still at cottage 6 in the picture means the clerk answered nobody, so the problem 2 pad now says the clerk must be at work.

I gave the bird the “move up 5” message and nothing happened. But also the point of this activity is the user should come up with the solution: for problem 2 the user trains a robot that receives [cottage-number | bird], computes cottage-number+5 and gives it to the bird; this robot is sent to the clerk, who asks each guest for its number and runs the robot with the appropriate box.

Problem 2 is the player’s: a fresh robot dropped on the moving office, a glass house by the desk, is taught there on the office post — take the letter, +5, give the number to the bird — and works inside. Ring the bell is a behaviour that gives every housed guest the pad once and switches itself off; the guests write [where I live | bird] to the office. The answers lie by the fence. A house dropped on its own door is refused instead of hanging the page.

I still find infinity resort very confusing — can you make a meta example that solves it?

meta/resort-teacher: a team of three at the yard’s table, given a thirteen-hole box, seats the guests, teaches a little robot the clerk’s job and puts it to work on a pad’s panel, rings the bell, teaches another the mover’s job and puts that to work, and welcomes five more. Three robots because a lesson takes a letter off a post, and a thought about a post is what waits for it. Found on the way: a guest hearing the bell before its address now keeps the pad for later; a set position mid-glide was being treated as a step; a folded tray took a robot’s work spot.

Explain the idea of ringing the bell — there wasn’t anything like it in the original, was there? Maybe you should look at the original city and the solutions; I have the feeling you’ve made it more complex than it needs to be. Go ahead — a robot could give a trained robot a box, but better might be to put them into a house and turn the house on (which is like trucks).

The city read robot by robot: the player’s robots receive the letter itself and go to the Solution bird; the machinery runs copies of them. So the resort has that shape now: train a robot on a practice letter, give it to the bird to the front desk or to the moving office; the desks are houses whose machinery runs a copy of your robot in a fresh little house per letter, with Tidy behind it, and the house folds away. A robot is a letter too, a claw can form a team, a house has no floor of its own, and the resort teacher is one robot again.

The tooltip should mention the label if the bird has one — there are probably other tooltips that should be enhanced similarly.

Every named thing’s tooltip now begins with its name, unless the line names it already.

Go ahead with the cloud: a mist obscuring cottages 12 and up, so the resort is seen to go on for ever.

The mist: eighty see-through puffs from just past cottage 11 to the fence, thin at the near edge and thicker in, with cottages 12, 13 and 14 half-seen inside; a guest sent further walks in and is lost to view. A model part may be see-through now, drawn unlit and shadowless.

I asked ChatGPT Codex to test ToonTalk 3D; read the report. Regarding #4 I now think the robot should not start running as soon as Ruby has erased enough that it matches — the user may intend to erase several things, and it is easier if the robot waits for the Start button.

A loosening no longer sets the robot going; the card says Start runs it. A number fresh off the stack takes the first digit typed as its value. The manual’s Enter and first-project steps match the workshop; the loading overlay leaves the accessibility tree; the manual’s little workshops open with a line about their experiment.

Revert #3 and fix the manual so a 1 typed 2 is 12. In close-up a second Enter should make multi-line text and Ctrl+Enter restore the camera. Pause should stop all robots but nothing else. A malformed or misspelled message to a thing’s bird should give error feedback. The turtle trail passes into the table after being vacuumed and dropped.

Digits go on the end and the manual says so. Enter in the close-up writes, Ctrl+Enter comes back. Pause stops the robots and nothing else, a paused run included. A letter a thing did not understand is said so even when a robot inside a house sent it. A turned trail or model is lifted to the table top.

Go ahead with the small-screen layout fixes and the first-project guide. “As big as the ground” isn’t a good name when not out in the yard. What did you think of a button for resetting the camera to the initial position?

Cards keep inside small windows and scroll inside themselves, one column on a phone, Marty’s panel between the cards in a short landscape. The first project is guided in the workshop, each step said as the one before is done, with a ring on the thing to reach for. A home-view button and the Home key put the camera back where it starts. The fit button reads “As big as the table” indoors.

Some task has been running for about 20 hours.

Here are more comments from ChatGPT after making those examples (I've asked it to make kid-friendly versions)
[ChatGPT’s eight suggestions, pasted — 17 lines]

My opinions: ignore 1, investigate 2, 3 would be very nice, 4 should be for robots to do so ignore, 5 in general maybe we need a settings button where this and other features can be customized, 6 sounds good - what do you think?, 7 not sure what this is about, 8 let's postpone but maybe we need a way for a robot to put up a GUI and to read its values (probably as a box from a bird) when the user closes the dialog box.

Of ChatGPT’s eight, the ones Ken kept. A world file’s things now load exactly where the file says — the shove that keeps a hand’s near miss clear had moved the garden’s pens a row back from their pots — and a model’s plaque is measured to the model, so a pea-sized planet no longer wears a plate wider than its orbit. Ideas for the sculpture, the Instant tick and a robot’s dialog box went back to him to weigh.

If I understand your idea for 3 it won't work for a "sculpture" that has parts widely separated. Another idea (that I'm not sure is good) is that when building such a thing that instead of pen up you set the pen color to 100% transparent and then restore instead of pen down.
6 fixing instant mode sounds good
we could experiment with 8 as a message to the computer bird
ChatGPT redid the examples in C:\Users\toont\Documents\New project\toontalk-learning-examples - what is your opinion?

At Instant a frame now ends only between rounds, so a round that moves several things is never drawn half done: apart on 1,057 frames of 2,256 before, on none after. A world with an introduction and nothing wanted opens as an introduced example rather than a puzzle, which ChatGPT’s worlds had exposed. The redone examples were read and run, and judged the idiom a person would write; Ken’s invisible-ink idea was preferred to Claude’s for the sculpture.

[set | pen | invisible] (or transparent) - sounds good - may as well support both invisible and transparent
I rather stick with hole numbers - works across languages (remember that at some point we should address localization)
Can you integrate them with the released examples and feel free to fix the 36000000/1000000 issue but check with me about any other changes

Invisible ink: [set | pen | invisible] (or transparent) keeps the pen drawing unseen, so a drawing with parts apart stays one trail for Dusty and one thing to save, and any color brings the ink back. ChatGPT’s three lessons — the planet, the flower and the spark — joined the examples through a generator of our own, numbers in lowest terms, hole numbers kept.

If the user closes the Marty card it should not reappear even if Marty continues commentary on a robot's actions.
In this conversation with Marty it claims text pads need a new message type:
[the exchange with Marty, pasted — 2 lines]
If so please add it.
ChatGPT did the puzzles - I'm attaching its report - let's discuss any suggested changes

A robot in a house now reaches your notebook on the table instead of pulling it inside — which is why the year puzzle’s judge had never got the date. Pads answer [set | text | pad] and [query | text | bird], so a robot can rewrite a pad’s words, which Marty had said it could not. Marty’s commentary no longer reopens a card closed by hand. ChatGPT’s puzzle report was read and its suggestions put to Ken.

📷
Your 1 is ok - this reminds me that that message is only useful a few times - a user who has used Ruby several times will be annoyed hear it - I think this is true for other responses and comments.
do 2
3 let's re-order the names
let's come back to 5 after I've done some testing
Is there a way for a robot to find out the number of holes a box has? Is the only way for a robot to access the Nth hole is to drop the box on N and then remove the item from the first hole of the second half of the box? I tried it and I think the order shown in the screenshot isn't intuitive - the box parts should be in the same order
I wanted to use Ruby on a box to make it any number of holes - I only was able after making all the holes accept anything. But if Ruby is aimed at the box and not a hole the condition should be any box.

Puzzles are numbered in play order (the year puzzle became p12), and the Ruby and Dusty how-to wears out once a visitor has loosened a thought three times. [query | holes | bird] tells a robot how many holes a box has; the halves of a split box stand in order; Ruby aimed at a box’s own frame makes it any box. From ChatGPT’s review of the examples: hole labels in brackets on the trained-actions card, and the lessons and READMEs tidied.

Let's do 4 now and I'll think about the others
Also can we add a new example that is a random color. It should work by having a robot on the back that uses a die to pick a color from a list of color names (initially the 7 rainbow colors). And why not use the color for the background (though we should have a contrasting text color). We'll try it so when turned on it runs full out but maybe we'll want to add delays

Random color: a pad whose Painter robot rolls a die each round, picks that color from a list of the seven of the rainbow, and paints the pad’s background with it and its words in a contrasting ink. And the examples gallery: 57 worlds in seven groups, in the order to learn them, each with what it teaches, a picture, how to run it and one change to predict.

@"C:\Users\toont\Downloads\bounce.text.thing.json"
Regarding discussion items: 1 yes, 2 agree - no change; 3 yes;

random color is working - can we replace hot pink in the flower example so each petal has a different color

If the user has provided their name and then clicked on an example in the gallery then it shouldn't ask again for the name and display the free play button. Also changing the URL means that refresh restores the example rather than a fresh state.
I have no idea how my notebook now has over 1800 pages. they seem to all be [query | time | _] except for the first few pages. Not clear how to fix this.
I'm wondering if the gallery should be added to the puzzle and free game panel.
I wonder if for brand new users something should show up so they can set some flags such as speech input and output, drop hints, and smart camera and perhaps also to customize Marty
Up arrow for a box makes sense, especially when zoomed, to more easily see the contents - a second up arrow does just show the bottom which is useless but ok
Attached is bounce where I put the robots and box on the panel - but it doesn't run there. I think all the behaviors should be packaged as being on a panel. And I think we should generate iconic images conveying what it does (e.g. bouncing).

The flower’s six petals take six colors from a queue on a nest. A pad whose panel has a robot at its desk is a behavior, as Ken’s hand-made bounce is. A world opened from the gallery asks no name of a known visitor and comes off the address, so a refresh starts fresh, and the door card offers the gallery. For the 1,800 identical notebook pages: Dusty with Shift takes every page that reads the same.

In the gallery use titles that are more readable. E.g. instead of " activity6-all-rationals" use "All rational numbers" and "resort-infinity" should be "Resort Infinity"
First project starts well but after picking up a 1 from the stack it doesn't highlight the 1 on the work area. And then it should highlight the leave thought bubble and so on. I think we need a few more projects like this. Maybe after completely the first one a menu of a few more projects appears.
Go ahead with the first-visit card and the SVG images on anima-gadgets
Regarding the open-bench worlds you are right but I think it should start with the robots and box in a panel which instructions to go through the door to watch it work

The first project’s ring now follows the hand from step to step, and three more projects come after it, offered on a card when the first is done. A settings card greets a new name. The anima-gadgets wear SVG icons, the four behavior worlds start as a star with its robots on its panel, and the gallery’s titles read as titles.

@"C:\Users\toont\Downloads\workshop.world (15).json"
I put the ellipse panel on the star panel and it works but Mimi vibrates since I guess she is working inside the gadget. As I was testing it saw a small and a large ellipse as I took out panels and put them back and used the knob. And one time it did part of an ellipse and then moved to the right. Attaching the world.

A panel set down on another panel’s work spot stays a panel across a save — a ticker that takes the enclosing thing as its own — rather than becoming a house of forty rounds a turn, which is what drew the ellipse small and large. Mimi mimes only the table’s copier, so she stands still for copies made out of sight. The gallery, the ledger and the index got favicons of their own.

More comments from ChatGPT - they look good to me

ChatGPT’s gallery review, taken whole: the album card describes the notebook it is, “Start this world over” is named as the button is, the introduction is said once, and each card says what you do — try, change, read or build — apart from what is inside, with a search, sections and a “tried” tick.

Here's a big more from ChatGPT before I ran out of credits:
[ChatGPT’s progress notes on the gallery, pasted — 9 lines]

From ChatGPT’s second batch: the Watcher’s note names hole 2 as its steps do, the ellipse and turtle cards say to drop on the star’s edge, not its middle, and a robot that stops while its houses are still at work says so — its part is done, N houses are still at work — instead of looking like an error.

@"C:\Users\toont\Documents\New project\puzzle-audit\gallery-runtime-review.md"
Another ChatGPT report. Regarding #3 perhaps a final reading of a text pad could address this. Or when appropriate the robot vacuums up its box if is no longer useful.
#4 has some good points. I too find it finicky to turn houses on and off using the switch. Bigger would help but maybe there are other solutions. A robot should not try to give a bird something if it is out on delivery. Perhaps the default size of pads should be larger so it is easier to get the desired kind of drop. I think there is a way to move the notebook - perhaps it should be made clearer and easier to do.
the rest looks good
Since you generated suggestions for ChatGPT to check it has finished going through the gallery - so regenerate an updated list

From ChatGPT’s runtime review, Ken’s picks: a teacher that ended by reading a pad keeps those words as its stop line; a bird out on delivery leaves a translucent stand-in that takes what is given and hands it to her on return; a click within 12 cm of a house’s lever is the lever; “Move my notebook aside” is in the menu. From its performance audit: numbers made out of sight stay unbuilt until seen, and fifty houses share each frame fairly — forty had never run. An updated list of checks went back for ChatGPT.

See report.md in C:\Users\toont\Documents\New project\regression-followup and perhaps other files in the folder
And maybe after that update the images in the gallery as planned

ChatGPT’s regression follow-up: saving says what to wait for, a drop on a filed picture files on its page, success is said first, the resort teacher’s last pad is right, and the title card folds on a short window. Then all 57 gallery pictures were reshot with the camera fitted to each world’s things, desk and robot.

what is left to do?

A question answered: the open list — one suite check failing on its timing, the things Ken had deferred, ChatGPT’s suggestions not yet done, and the ledger behind.

ChatGPT did run the tasks in your list. Didn't you see it in C:\Users\toont\Documents\New project\regression-followup ?
We never did problems 3 to 5 for Infinity Resort (I can find the URL for the original ToonTalk describing them if you need)

Answered: that follow-up had already been acted on, and the “waiting on you” line was wrong. Two more of ChatGPT’s example sets turned up in the same folder, and Resort Infinity’s problems 3 to 5 were taken on, pending the original’s description.

https://toontalk.com/Tools/Infinity/Doc/resort_infinity.htm and https://toontalk.com/Tools/Infinity/Doc/resort_infinity_guide.htm
Yes, regenerate the 3 lessons ChatGPT made to fit everything else

Resort Infinity 3, 4 and 5, from the original’s pages, each world opening where the last one ended. ChatGPT’s garden, clockwork and fountain were rewritten in the workshop’s own vocabulary, and a behavior saved running opens running. Six new cards in the gallery.

@"C:\Users\toont\Documents\ChatGPT Projects\ToonTalk 3D\resort-smoke.cjs"
ChatGPT produced the attached and several files at C:\Users\toont\Documents\ChatGPT Projects\ToonTalk 3D\toontalk-examples

Teacher worlds for problems 3, 4 and 5, each on its own resort yard. Every resort teacher now waits for the bell before letting the newcomers in, and the suite’s resort-teacher check passes again.

Last month you generated a version that claude.ai could copy into an artifact so Marty can run without an API key. At the time toontalk-3d.chat.html was about 500KB so the maximum artifact size of about 1MB wasn't a problem. Now it is almost 1.5MB. In other projects we worked around this by pulling out resources and data from the HTML file. Then the first time the user used the artifact they would be instructed to upload a file that would be cached in the browser's storage. Can we try that now?

The chat artifact became a shell and a pack: the module minified from 1.25 MB to 535 KB, and the models, Marty’s manual and the puzzles in toontalk-3d-pack.json, dropped on the page once and kept gzipped in the browser. The shell is 560 KB.

please update making-of.html - include a section listing the innovations from the original ToonTalk and a section about the help from ChatGPT's testing.

The making-of gained two sections — what was not in the original ToonTalk, and the tester who never slept, on ChatGPT’s rounds of testing — with the figures brought to 20 September.

📷
gallery.html explanation of the markers in the attached needs more line spacing for that section

More line spacing under the legend’s chips in the gallery.

It is time to make https://toontalk.github.io/toontalk-3d/ point to the current version.

The site’s root is the workshop: index.html points at toontalk-3d.html, and the August snapshot stays as history. The compressed resource pack for the artifact went in beside it.

@"C:\Users\toont\Downloads\files.zip"
Artifact created but it took a bit of effort (see attached).
please remember for the future the issues resolved around keyless API usage in artifacts

The published artifact’s keyless brain is the sample capability, ported from Ken’s claude.ai session: the pack is fetched from the site first and asked for only when refused, a dropped .gz or .json both work, and the gallery’s links are absolute. The keyless-artifact lessons were saved to memory.

@"C:\Users\toont\Documents\Codex\2026-09-21\use-the-open-edge-tab-at-2\outputs\marty-test-report.md"
ChatGPT tested Marty. I assume some shortcomings are coming from gpt-5.6-terra but perhaps the prompt can be improved.

The first finding seems to indicate that Marty's prompt hasn't been updated to reflect that after Ruby erases the robot doesn't run automatically.
Another example of the same sort is what happens when typing '2' to '1'

I also asked ChatGPT to try the artifact version:
[ChatGPT’s comparison of the two versions, pasted — 14 lines]

gpt-5.6-luna is a good current default for OpenAI; Claude is ok; Gemini should be gemini-3.8-flash -- how can these defaults be updated after the release (is it worth a web search to find the best cheap model from each provider?)

Both of the worst failures were the app’s, not the model’s. Marty’s robot demo now presses Run itself and reads the desk — the script still said “4, 5, 6” from before Ruby stopped starting runs — and a building partner can fetch one fresh thing from a stack and may claim nothing else. The prompt learned that digits append and that erasing never starts a robot; a stale Show-me offer clears; the provider selector stops showing the wrong provider. Defaults are gpt-5.6-luna and gemini-3.8-flash, and a served page reads marty-models.json at boot, so they can change after a release.

Let's remember to do more of the puzzles from the original toontalk later.

Noted for later: 39 of the original’s 74 puzzles are ported, and the rest wait until Ken says go.

I'm going to ask ChatGPT to generate a few short (20-60 second) video demos of ToonTalk 3D. It can have captions. Can you produce a list of suggested videos

VIDEOS.md: a list of short captioned demo clips for ChatGPT to make.

please redo the making-of.html with bookmarks and a table of contents so I can link to sections. Also when referring other files provide links (e.g. to BACKS.md) When linking to a markdown file use github.com for the URL and github pages for other files. And add a section about ChatGPT testing Marty as well.

The making-of got a bookmark on every section, a table of contents, its files linked (markdown on github.com, pages on GitHub Pages) and a section on ChatGPT testing Marty; paragraph spacing and an overflow on narrow screens fixed.

I think long ago I provided a link to information about anima-gadgets including something written by Miki - can you find them?

Found in the ledger: Ken’s own prompt from the anima-gadgets round, with behave.tt and the archived IOE Playground library list; Miki’s write-up had been folded into BACKS.md. Nothing changed.

can you find the testing results from ChatGPT that I uploaded here

ChatGPT’s testing reports, found among the uploads, were saved to the repository.

I’m wondering how feasible it would be to enable a “voice control” mode. A user could speak (or type) things like this:
Pick up a 1 and put it in a 3-hole box.
Create a text pad with “ToonTalk” on it.
Give a robot a scale with 1 and 100 on it.
I’m assuming a key has been provided to an LLM API. Marty would do this if the option is enabled.

A question answered: very feasible. The hands, the wish-to-plan-to-act loop and the listing of what is on the table already existed; new would be a schema of about eight verbs, a prompt of the workshop’s rules, and an executor that checks a plan against the table before anything moves. About a day.

I now think this should just be an alternative way of controlling one's "hand" - Marty won't be involved. My idea is that the LLM decides questions such as "a 1" vs "the 1": I'd read a as fetch fresh, the as on the table." based on the context.
Right - this will only be an option if an API key is available (though perhaps Gemini Nano in Chrome can do a minimal job?)
I've released this version so don't touch https://toontalk.github.io/toontalk-3d/ - create a new file name

The design settled: not Marty but your own hand, the brain reading “a 1” as a fresh one and “the 1” as the one on the table, and only when there is a brain. Work began in toontalk-3d-next.html, a copy, leaving the released workshop alone.

Perhaps I don't understand how to turn the feature on.
[the exchange with Marty, pasted — 5 lines]

What Ken typed had gone to Marty, who cannot move the hand. The feature lived only in the new file, behind a switch in Settings, with a line of its own at the top of the screen.

Nothing happens but the responses seem ok
[the exchange with Marty, pasted — 4 lines]

Pushed: toontalk-3d-next.html — your hand, by word: a sentence, a brain, and your own hand makes the moves, every step checked and the first failing one named. The switch went into the ⋮ menu where it can be found, and Marty was told to say he cannot move the hand rather than claim he had.

Still not working - I did enable move my hand by word.
[the exchange with Marty, pasted — 3 lines]
Also does it matter if I use the workshop or Marty's microphone button? But behave the same. And the workshop microphone button isn't always available

The hand’s line follows the visitor’s name, and a hand sentence said to Marty moves the hand — either box, either microphone.

It is working. But when I tried "put the one in the copier" it said it didn't know about a copier. I tried "give the one to Mimi" but it said that Mimi wasn't available.

Is there a way to keep the microphone on? Would a pause be a good signal to process what was said? Or a special phrase like "do it" (user customizable) might be better.
Also it would be nice to see the request and response (and to scroll to older ones)

The hand knows Mimi and Dusty; the microphone stays on, and a pause or a go phrase sends what was said; and a log under the line keeps each sentence and its answer, scrolling back.

📷
a task has been running for 19 hours
why didn't "give" work in the attached?
It started repeating itself in the following. and "copy it" didn't work
[the hand’s log, pasted — 12 lines]

Give now finds the only robot on the table. The desk is a place, “leave” steps out of the bubble, and the microphone ignores the page’s own voice — it had been hearing the workshop’s answers and sending them back as sentences.

📷
Why did you write "the brain wasn't told that Mimi is outside the bubble" when Mimi is inside (see screenshot)
I still see the 19h task.
Earlier you said you couldn't test this feature but you don't need to use the microphone - just enter text instead. Please do some testing and report back.

Inside a thought bubble the hand is the robot’s claw: the robot’s own desk, work spots and Mimi are listed and used, and the claim that Mimi was outside was withdrawn. Tested by typing, as Ken pointed out it could be.

📷
there still is long running task (screenshot)
Maybe I'll test this using the Claude extension to Chrome so that way different API providers can be tested. But will this get in the way of reading email and other tabs?~
Can you generate a report to give it instructions on how to do the testing

TESTING-HAND-BY-WORD.md: instructions for a tester with a real brain — the sentences, what each should do, how to tell a brain error from a hand error, and what to report.

📷
I'll test this on my laptop.
Why did you write "make a 12 a number 12 (a fresh 1 typed 12 — not 112)"? typing '2' to a fresh 1 is how its worked for several days now.
Now there is no 8311 localhost for testing
"E3 take a robot refused: a robot cannot make robots inside its thought"
If a robot can train a robot why can't it make one and then train it?
"E4 leave refused while the claw holds something; empty the claw first (put it down), then leave works and the world rewinds"
You can leave while something is held
explain "Naming things by word (a nest called "orders") is not done yet." - I don't remember this.
"Ruby (erasing parts of a thought) and Dusty on parts of a thought are not reachable by word." why?
"Going through a panel door, the yard, and the notebook are not reachable by word." why not?
the corner card (screenshot) should have a button for seeing a log of everything said.
When I tried to train a robot to put a fresh nest/egg on the perch it says there is bird on the perch.

Answered, and built in the round that followed: the hand names things (“take a nest and call it orders”), sends Ruby and Dusty at a thought, goes through panel doors and out to the yard, files in the notebook and takes back, and leaves a bubble while holding something; “What was said” on the title card opens a log of everything. The “not 112” line was the doc’s, not the app’s; no reason was ever recorded for robots not making robots; and what a nest on the perch should mean was left to Ken.

I've tried 3 times but keep seeing "Remote Control couldn’t connect
Try again in a moment."

Remote Control had been stuck connecting on this end, and was switched on again to try.

I closed the app on my laptop and opened it again but didn't see this chat. Then I searched for it, found it, and it claimed it was archived. I unarchived it and now it says the computer running this is offline (which clearly it is not)

Not fixable from inside the session: the link from this desktop to the relay was timing out, which is why the laptop saw the computer as offline. Four things to try, in order.

I did 2 and 3 and no luck. I don't see a remote control switch in this session's toolbar

Still timing out, on the relay from this desktop; retrying stopped. Testing on the laptop needs no Remote Control: the next build is on GitHub Pages and the tester’s instructions are in the repository.

I used Fable 5.1 - Which Claude model should I use for more testing?

The first tester’s report (Claude in Chrome, with gpt-5.6-terra as the brain), all seven findings handled: a set-down finds clear table and says where it landed, a pad’s riders survive a daydream, things in holes are numbered, desk, platform and tray are places, a full desk refuses before the gift, and a bird comes with her nest. For more testing: keep the tester, and try Sonnet 5 as the brain, since that is what visitors get.

I'll test Sonnet as an artifact later (once we get this feature working well). Gemini Nano test did not go well:

[the Gemini Nano tester’s report, pasted — 30 lines]

By the way, do keyless artifacts hardcode which Sonnet model is used or will it use new ones as they are released?

Every recommendation in the Nano report went in. Marty hands on the visitor’s own sentence, never his paraphrase, and reports how it went. The hand forgives a weaker brain’s wording — “pickup boxes” means take from the stack, a kind’s name means the only one there. Failed turns stay out of the history, five worked examples are in the prompt, and things are labeled #1, #2 so they cannot be confused with the number one. And a published artifact asks for a tier, not a model, so it follows Anthropic’s releases.

update the testing instructions for the Nano rerun (include some of the new functionality added yesterday)

The tester’s instructions for the Nano rerun: setup for the built-in model, what changed since the first run, the same sections first for a like-for-like scorecard, and a Section I for what is new.

I don't see any section I?

It was there, between Section H and What to report; Ken was looking at an older copy. The section was pasted into the answer.

Here are some test results for the older version: https://docs.google.com/document/d/1mjJcQ19vwto8Q-qxIoGROSpl_zSK2t8jz7SH7vwzdBA/edit?usp=sharing

From the older version’s results: “+” no longer zeroes a number, “run” fails unless something ran, holes count from 1 as the robot’s steps do, and the prompt tells the brain to do only what was said.

Here's some more test results: https://docs.google.com/document/d/1YnxsZ6TBjSMhnPWrdO76-XOS6H-WSGlYgwz8CLW8iVQ/edit?usp=sharing
I'm not sure I understand your questions - elaborate

From the next results: riders and trays appear in the listing, a panel’s own things are told from the table’s, “.” in the line stops a run, and the hand sets down what it holds before waking Dusty and ends empty. The questions put to Ken were spelled out.

1. The robot should end up trained (to do nothing). Perhaps a user wants it as a placeholder to replace later. If part of a team then the erasures matter. This is how the original works too.
2. The double labeling is fine. Dropping a bird's only nest on a notebook works fine. But a bird without a nest when given something should fly off, destroy the thing, and return - not report a problem. When a bird is placed in a notebook (without the nest in the same object) then it correctly creates a nest for the bird when removed. But giving something to the new bird should only fly to the new nest and not also the original nest.

Maybe during testing it should be running at 8x so the animation doesn't take much time. "instant" works too.

In the following there was a 1 on a nest that was on the table

[the hand’s log, pasted — 8 lines]

Ken’s answers, built: a lesson that only erases trains the robot to do nothing, as in the original; a bird with no nest flies off with what she is given and comes back without it; a bird taken from a notebook answers to her new nest only. And the hand now sees what stands on a nest.

I'll test the artifact - please make a chat version to copy to an artifact

toontalk-3d-next.chat.html: the next build as a claude.ai chat artifact, 600 KB, built from the released pack without touching the release.

https://docs.google.com/document/d/17X8yvYj1_umb44kfaNIuOEA33UI1RqPlSVsYZvENqoI/edit?usp=sharing is the Claude artifact test
Do you think it is worth doing more tests or is this feature working well enough? Do you think someone (perhaps physically unable to use a pointing device) could successfully use the app just with voice (and looking at the screen)?

The report was not the artifact test — the tester had run the Pages build with gpt-6-sol — but it found one real bug: “run” on a trained robot crashed in the desk comparison, silently. Fixed, and a step that throws now reports ✗. Good enough with a strong cloud model; Claude in the artifact and Nano still to test. Voice alone was not yet possible end to end: positions, the camera and the controls off the table were missing.

add camera verbs, positions in the listing, and spoken results

For voice alone: the listing gives screen places, the camera moves by word, questions about what is here are answered, and answers are spoken when the sentence was.

This didn't work right:

[the hand’s log, pasted — 10 lines]

[the hand’s log, pasted — 10 lines]

What stands on Mimi’s platform is listed, and a drop onto it takes the original off first. The notebook, Mimi, Dusty, the desk and the stacks are places the camera can look at.

I didn't say "a room on the table" - the app did

The microphone had heard the workshop say “A robot on the table” and passed it on as Ken’s “a room on the table”. It goes deaf while the workshop speaks and listens again when it is quiet.

Here's a slightly out-of-date report on the Claude artifact running the tests. https://docs.google.com/document/d/1BzTrVzopDpxDhZzbZqCDvSGH9hzNigifMYRaLxJp_9k/edit?usp=sharing
By the way, I'm pretty sure artifacts don't permit access to the microphone (it says "not allowed") - are there any workarounds? In any case, the artifact is good for testing.

From the Claude-artifact report (25 of 30): “open” opens the named thing’s panel, things a plan makes get the next label, birds can be given things, and the robot at the bench is listed with a number of its own. The microphone cannot work inside an artifact; a refused one now points at the computer’s own dictation.

Let's add advice to the artifact when a user clicks on the microphone telling them how to use the operating system's speech recognition

Where the page may not use the microphone, clicking one explains the computer’s own speech recognition — Windows+H, Fn twice on a Mac — and puts the cursor in the right field.

After using Window's speech recognition successfully with Marty I tried it with move with words (by the way "by word" should really be "by words" in the interface) and it worked once and then I needed to click in the input area to give the next command.
The "go phrase" doesn't make much sense in Windows where "press enter" is built into the recognizer
The log of the hand by words should not be visible by default
I couldn't get it to put the 1 back after copying it:

[the hand’s log, pasted — 17 lines]

The hand’s line keeps the cursor while the hand works, so Windows dictation can carry on. “By word” became “by words”; the go phrase is offered only where the page itself listens; the log opens only when asked. Inside a bubble an empty desk takes a drop, and the original can be put back after Mimi copies.

Working pretty well. After training the robot and running it when it stopped because it didn't match the thought bubble I needed to restart the speech recognition. But then I couldn't erase the number:

[the hand’s log, pasted — 28 lines]

After a run stops on a mismatch, the hand can erase and remove parts of the bench robot’s thought, as the workshop’s own advice says to; the listing gives that thought and says when the desk no longer fits it.

I trained the robot, erased the 1, and ran but I couldn't stop it. I stopped it by hand. Then when I asked it to change the speed the number the robot was working on disapeared

[the hand’s log, pasted — 50 lines]

“press Enter” typed by dictation is dropped from a sentence, and every sentence is logged. While a robot runs the hand takes only speed, pause, resume, stop and the camera, and “stop …” stops it — “speed up by 8” had been planned as a drop and a give. The claw sets down before picking up the original.

Working better but still couldn't change the speed. and "return the one" didn't work.

[the hand’s log, pasted — 42 lines]

“Double the speed” and “halve” are steps from the speed shown, and “return it” reads as “put it back”.

stop the TTS

Not this session’s speech: nothing here was speaking. The settings that read the hand’s answers aloud, and how to mute the tab.

You did stop it. And it was coming from this app not the browser since it was reading your previous response

Most likely Windows itself — Narrator or Voice Access — with how to stop each.

Why is my Google Drive have recent files such as 000004.log containing [its first line, pasted — 1 line]
and cv__debug.log which starts with [its first line, pasted — 1 line]
If you are producing them could you remove them when they are no longer needed? If not, what is producing them?

The files were Codex’s: two Edge profiles it had made in Documents on 21 September, which Google Drive backs up, and a headless Edge still writing into them. It was stopped and both folders deleted (549 MB). The same round took in the 25 September artifact test (keyless Claude, 22 of 29): nothing typed is lost — a sentence waits its turn and stop acts at once; a failed plan is undone, lesson and all; the answer says what a drop added up to; a full desk is cleared first; leave leaves a panel or the yard; and Marty names the switch when it is off.

Another test report. https://docs.google.com/document/d/1eUulaFn959UKzKsmNhAw7pQgoT7D8VQGeyEvOn2iFao/edit?usp=sharing
I wonder if we should keep testing and tuning or if this is enough. Can always come back to this after some real world tests. Or is it too unreliable for users to use?

The link was the old report, from before the fixes. The advice: enough for now — opt-in, forgiving, the worst failures closed — after one short run to confirm the last fixes, and with Gemini Nano treated as not good enough.

This looks very good, right?
One thing I'm wondering about is whether it might be worth exploring bigger more capable models than Gemini Nano that can run well in a browser. The download could be cached. Is it likely to preform well enough to experiment?

The right report: gpt-6-sol, 30 of 30, no hand errors, about 2 s a sentence, with a handful of small things left in what the brain is shown. A bigger model in the browser judged worth an experiment: WebLLM, 4–9B models, downloaded once.

small fixes first but let's do the WebLLM experiment right afterwards

The small fixes first: all or nothing in the prompt, Mimi’s copy told from the original in the listing, robot spots named, finer places and which of the boxes, and a new sentence clears an old refusal. Then the WebLLM experiment: a model in this browser as the brain, with a model picker, a download-once button and JSON held to the schema — about 5 s a sentence instead of 28. tests/hand-scorecard.js scores any brain by the workshop’s own state: Qwen 3.5 4B 23/38, 9B 21/38.

Any theories about why 9B performed worse than 4B? Is it worth exploring whether there are other models that might perform better? Don't bother if it is unlikely.

Theories: mostly noise — 38 linked sentences, and the 9B’s early naming slip copied through a section — with thinking turned off and a prompt tuned for big cloud models as likely handicaps. Other models in WebLLM’s range were unlikely to do better; thinking mode was the one cheap experiment left.

yes, try thinking mode

Thinking mode tried and taken back: left free, it thought for 230 s and made no plan; kept brief, it scored 8 of 17 against 12 without, and slower. Written up in BACKS.md.

delete the 7.5 GB

The test Chrome’s folder with both downloaded models, about 7.5 GB, deleted.

can you update the making-of.html and the like with a new section (and column for the statistics) about the telling the hand what to do

The making-of gained a section on telling the hand what to do, and a third column in its figures for 21–26 September, with prompts and tool calls recounted by one rule for all three columns.

yes, bring the ledger up to date. And let's release this version (so its at https://toontalk.github.io/toontalk-3d/) and update the manual.

The ledger brought up to date, day headings and all; the next build released as the workshop at toontalk.github.io/toontalk-3d, and the manual given the hand, by words.
