this is a magic eye illusion. use this project on full screen. at the beginning, you will see a grid of squares. hold the screen in front of your face and relax your eyes. then slowly, very slowly, move the screen away from you. what happened? did one of the columns pop out at you? if yes, then good job! if no, then two things: one, some people can't see these illusions. two, it takes a LOT of practice. when your ready for a bigger challenge, hit the space bar. you will get a moving illusion of sprites. it's the same, except that instead of squares you will see max the sprite, who changes costumes every second.
