Here's a page of interesting optical illusions, most of which involve the appearance of motion in a static image. Link via Chicago Boyz.
Here's another similar one I came across recently. And while I had seen this one before, it's cool how the image just appears, coming out of a black field of closed-eye "vision". No, it's not a religious experience. It's just slightly cool.
