This is the photomosaic screen saver on my macbook. It's frickin' amazing to just sit and watch. It works off of all the photo's in my iphoto and makes them into another picture which then is a part of the next mosaic and so on and so forth ad infinitum. It's a real facemelter. It's better in person, so next time you visit ask me and I'll show you. It's like a damned time machine. That or the acid is really kicking in.
