A discrete event simulation of balls colliding elastically in a closed box. For some reason, I've had the idea of making this ever since Prof. Luc Devroye said, and I paraphrase, that "every student should experience writing a discrete event simulation before graduating."

The applet gives you choice to render discretely or continuously. If you choose to render discretely, a pause of 100ms is taken during each event. Continuous rendering may be choppy with large numbers of entities.

Hit the reset button to read input parameters and restart the simulation.
