Bouncing balls in a heptagon · llama-3.3-70b-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.

This code creates a canvas element and gets a reference to it. It then creates an array of 20 balls, each with a random initial velocity and rotation. The `draw` function is called repeatedly using `requestAnimationFrame`. In each call, it clears the canvas, draws a heptagon that spins 360 degrees every 5 seconds, and draws each ball at its current position. It also updates the position and velocity of each ball based on gravity and friction, and checks for collisions with the walls and other balls. If a collision is detected, the ball's velocity is reversed and its rotation is updated. The ball's spin is also updated based on its rotation.

EVALUATION
Only an empty rotating heptagon with a center dot is shown; no numbered balls, gravity, or collisions appear.

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.
