Bouncing balls in a heptagon · gpt-5.6-sol

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.

EVALUATION

3/5 partial

Rotating heptagon with numbered balls under gravity/friction settles under rotation; balls fall and collide, but no clear input-specific interactivity visible.

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.
