Some random particle sim where each particle type has its own distinct properties and rules for changing into other particles. May be laggy on old machines.

Unfortunately, the particle interactions are not deterministic, though when one particle is hit with another, its _state gets the _state of the colliding particle added to it. Because of the two collision events being carried out separately and not necessarily in the same order, not every collision has one outcome. _state defines each particle as follows:

0: black, infinite friction, unbouncy
1: white, 0 friction, bouncy
2: red, 0 friction, adhesive
3: green, 0 friction, anti-adhesive
