I thought this was going to be a waste of time, but once it started I just couldn't look away. So simple, yet captivating. If you'd like to do something similar, try the same general setup, but use the color-contrasting patterns that make you see colors that aren't there. You know, like that one where you stare at a purple dot that orbits the center of a gray screen - after a few seconds, your eyes see green dots everywhere trailing the purple dot. It's so convincing, but the green dots aren't really there. If you can use tricks like that on top of everything you've already done, you'd have some pretty seriously funky/trippy eye candy. It's good as is, just sayin if you want something to take it up a notch, check into the kind of optical illusion I describe and add a few of those tricks. Great work! :-)
