Bouncing balls in a heptagon · seed-2-1-turbo
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.

thinking
I'll create a physics simulation with 20 numbered balls dropping from a spinning heptagon's center.All core features for the physics simulation have been confirmed, and I will implement it as a single HTML file using canvas and custom physics logic.

File written, will verify and summarize.
Created `/tmp/ws/index.html` — a self-contained physics simulation with: - **20 numbered balls** (1–20), each with a unique hue, dropping from center - **Rotating heptagon** (7 sides) spinning 360° every 5 seconds - **Physics**: gravity, air friction, rolling friction, realistic restitution (0.85) - **Wall collisions**: custom ball-vs-segment detection with penetration resolution, tangential friction, and spin induction from wall motion - **Ball-ball collisions**: custom circle-circle resolution with impulse-based response, mass-weighted positional correction, friction, and spin transfer - **Spin visualization**: each ball's number rotates with its angular velocity, plus a white dot marker for clarity - **Stability**: 3 iterations per frame for both wall and ball collisions - **Bonus**: click the canvas to reset No external resources — fully sandboxed. Open `index.html` in a browser to run.

EVALUATION
Heptagon spins and 20 numbered balls fall, collide, and settle in a pile at the bottom, but they lack visible bounce/spread dynamics.

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.
