BTW, I just put up a new simulation of rigid body dynamics and collisions. Basically you'll see rectangles moving around freely in a 2D region. The rectangles can bump into each other or the walls causing them to rebound and spin.

Can it do rigid bodies in three dimensions, when the three moments of inertia are different? It's alot of fun to work through the exact solution for zero torque, if you enjoy theta functions. __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful.
