GodSim - Bouncing People

I hope your Java Virtual Machine is feeling well. This is part coding project, part aesthetic shenanigans, and part investigation of the nature of God. Believe me, it's not easy to pull off. (If, in fact, I managed it.)

I'm not sure if I have the proportions of pagans to believers down, since it's really a guessing game. I actually think that Heaven fills up too quickly. Obviously, the criterion for getting into heaven is a little bit lax. What's your red value?

For the technically inclined:
4 Classes, 2 for the Sim and 2 utility classes. Doubled-buffered and threaded. The LinkedList class in the jdk was giving me grief trying to include it, so I wrote a simple one to avoid the hassle. The Sim classes are commented, but the List ones aren't.
