Adjust the variables and see the result! Some weird things can happen, especially if you turn on turbo mode... In v0.2 it got Trail Length for exactly that, and ART. If you want to know what it does, then turn it on! Try it with turbo mode too. v0.3 now has COMPLEATE CHAOS. Its... chaotic. ;) WARNING: Flashing Colors when drawing certain patterns. (low brightness when drawing spirals IF turbo mode is on) recommended.
The stars are in red, green, and blue because white light is made from those three colors.
