Adjust the tracerate and points, then press SPACE to start. Slowly but surely, an approximate Serpinski triangle should emerge. (This is a fractal pattern of Triforce-like shapes.) Accuracy and time needed depends on the inaccuracy and tracerate. The tracer operates randomly, moving half the way to a random point every turn, yet thanks to chaos theory it always traces out a Serpinski triangle.
