This is a screen saver I made some time ago. It started out fairly harmlessly, as a programming experiment to see if I could simulate gravity and acceleration on balls, making them bounce around in a believable manner. At some point the balls turned into sheep because the bouncing reminded me of those sheep you count just before you fall asleep. I really have no explanation why the final product ended up as it is, except that I find it quite entertaining (that probably have something to do with a childhood spent watching Road Runner cartoons)
