I was following the rigid body dynamics tutorial with the buttons forming a picture, but I got carried away halfway through. I wanted to see what would happen if I used thousands of buttons instead of the few dozen used in the tutorial. I must have done something wrong because this interesting effect happened: all the buttons would crash onto the surface, and then explode outward as if a force was pushing them away from the center. The upper half is a side view, and the bottom part is a top view.
