Based on Daniel Shiffman's (shiffman.net) recursive tree using arraylist.
This is a prototype for a physical computing project that will use cooperative game interaction to use a limited amount of water to spur the growth of a tree.
New Version, there's a problem with exponential growth, going to have to enforce population control :P
A post apocalypse scenario, in which humans repopulate the earth. Inspired by the zombie infection app (Carl Sverre).
Balls bounce with gravity and collide with one another. Collision response is still inaccurate, but I'm working on it. Once again, thanks to Dan Shiffman for the Vector3D library, which can be downloaded from shiffman.net.
