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.

I'm building a physics simulation in HTML with a rotating heptagon container and balls that interact with gravity, friction, and collisions—both with the spinning walls and with each other, accounting for rotational dynamics and spin friction. Let me work through the physics setup, starting with the container geometry and angular velocity, then defining the ball properties including mass and moment of inertia. Writing physics engine... Now I'm working out the effective mass for the tangential impulse—with the perpendicular contact point, the cross product simplifies nicely to give me 3/m as the effective mass. I'll apply both normal and tangential impulses to update the ball's linear and angular velocity, using the cross product to convert forces into torque. For the simulation itself, I'm setting up balls dropping from the center with staggered timing, using a canvas of 600x600 with a wall radius of 260 and ball radius of 16, then rendering the numbers rotated by each ball's orientation. Writing the simulation code...
