I've made a 2D physics simulation program. Download demo Press 'b' to add a box Press 'c' to show/hide contact points The average elasticity and friction would be some value between 0.2-0.6. You can see that boxes on the ground are not really resting. They're vibrating due to the small impulses. And some even spin like crazy without a stop unless it's hit. How can I fix the problems?

Can't you just test to see if the box's movement falls below a certain threshold and then flag that box as inactive (stop iterating it until it becomes active again)?
