Chain Reaction

This is a pointless, yet fun simulation to play around with. Hold the left mouse button down to spawn particles with randomized radius and velocity. When a particle collides with the edge of the window, it will explode in an arc of smaller particles which are reflected back onto the page—each of which will eventually explode into even smaller particles, and so on, until they reach a minimum size.

Right click to tweak various parameters. Beware that if you spawn a lot of particles, the framerate will drop to a crawl and your fans will probably kick into overdrive. The "Explosion Particles" parameter, which controls how many smaller particles are spawned when a particle explodes, is particularly devious.
