Stable box stacking
-------------------

This is a proof-of-concept demo of large, stable box stacks.

Prototyped in my old "ICE physics", but should work in any engine.

Solver uses 4 iterations.

The 50-boxes-wide stack eventually collapses in all the engines I tested (Bullet/PhysX/Havok). In some of them even the 30-boxes-wide stack collapses rather quickly.

In this demo however, even the 50-boxes-wide stack remains very stable. It also doesn't exhibit any of the weird motions or gaps between boxes that you may see in the other engines.

So basically it's the fastest & most stable stacks I've seen so far :)

Might be included in a future PhysX version, stay tuned!
