I've been messing with a stereogram program and I created a stereogram of myself. A stereogram is one of those three dimensional images hidden among a sea of dots that just sort of pop out at you as you stare at the picture. This is my first time using the program so it isn't that good because creating a "depth map" is pretty difficult, especially for the human face, anyway try to see it here. The best way to see these things on a computer monitor is to look at the picture but try to see your reflection in the monitor at the same time. Or put your face about 1 to 2 feet away from the monitor and look in the center of the picture and then let your eyes relax so they kind cross a little and the picture should jump out at you.
