Bouncing balls in a heptagon · gpt-5.6-luna
Show 20 numbered balls (1 to 20) dropping from the center of a heptagon that spins 360 degrees every 5 seconds. The balls are affected by gravity and friction, collide with each other, and bounce realistically off the rotating walls; show each ball's spin via the rotation of its number. Implement all collision detection yourself.

**Creating the index file** I need to start working on creating the `index.html` file. It seems like integrating canvas physics will be important for this project, so I'll need to implement that too. I should probably inspect the directory to see what files and resources I have to work with. Getting everything organized early would really help keep things running smoothly later on. Let's dive into this!

**Figuring out visuals and scaling** I'm considering how to align everything around a small circle, like a visual heptagon. I think I need to control the text and consider the canvas's device pixel ratio. I wonder if resizing will affect physics scaling, so should I keep coordinates normalized? I guess using the canvas coordinate system while resizing in relation to the center and radius might help. For the heptagon, I'm thinking a radius of min*0.39 and for balls, maybe min*0.032?**Polishing visual presentation** I see that I have a total area of 0.064, which is fine, but now I need to focus on making it visually polished. I’m thinking of writing the material using heredoc to enhance the presentation. That will help in formatting neatly, ensuring everything looks good and professional. It’s just a matter of arranging the content in a way that's easy to read and visually appealing. Let’s get this done!

EVALUATION
20 numbered balls fall, collide, and bounce within a rotating heptagon; consistent physics but no distinct input reactions.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
