Use Turbo Mode! Drag the four black dots around with your mouse, (some of them might be in a corner), and see how the pattern changes! Squares, Circles, Curves and other weird shapes will appear as you change the location of the four dots. --Deeper explanation-- This is a modification of a regular Voronoi Diagram, where instead of comparing distances, we're comparing the sin of the distances. This is the reason for all of the disconnected blobs of the same color, and also the reason for all of the weird patterns. I'm really proud of that one. Enjoy!
