Wheel of Trinkets

This movie is a (significant) modification of the previous movie (clumping). Here I'm using a simpler collision algorithm that doesn't allow the balls to intersect at all, and I'm keeping them inside a rotating circle with gravity.

Why? I'm trying to figure out the physics behind a kaleidoscope object cell. In nicer kaleidoscopes, you are looking at an oil-filled chamber filled with trinkets.

This is a 2d-representation of a kaleidoscope object cell (without the kaleidoscope effect). I intend to make an OpenGL version of this program, using 3D physics, which will make for a very realistic kaleidoscope simulation.
