Particle Simulation simulates a random explosion and shows the path the particles would take. Red is the hottest part of the explosion and blue/purple is the coldest part. Explosion size changes how big the explosion is and number of rays is the quality/number of particle paths printed.
Don't ask. I was bored. This works best in Turbo Mode. haha turning the number of rays up to 100,000 takes so long in Turbo Mode =D
