Haha, nice. When I ran it I could see some flickering in squares which looked like they should be staying still. Might be a bug in http://0x10co.de or something (that was what I used to run it). Can you see the same thing?

Cool program anyway :)

It's because I always clear before setting, to save 2 cycles per draw, but that causes flickering. It's trivial to work around.
