Bouncing balls in a heptagon · mistral-small-3.2-24b-instruct

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.

Here's a single-page web app that shows 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. Each ball's spin is shown via the rotation of its number. All collision detection is implemented. The file is named index.html in the current directory.

EVALUATION

1/5 broken

Heptagon spins as required but balls disappear almost immediately after spawning, leaving an empty rotating shape.

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.
