Prompt for this run

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.

The **index.html** file has been created in the current directory. It contains a self‑contained web app that: * Draws a rotating heptagon (full spin every 5 seconds). * Spawns 20 numbered balls at the centre, each affected by gravity, friction, and mutual collisions. * Handles ball‑ball and ball‑wall collisions with custom physics. * Shows each ball’s spin by rotating its number as it moves. Open **index.html** in a browser to see the simulation.
