If you ever enjoyed unfocusing your eyes to see a magical 3D sailboat, you might enjoy doing the same to play Tetris. Or it might make your head hurt and eyes water.
As we all know, Tetris physically changes your brain. 3D Stereogram Tetris on the other hand, will physically damage your brain. At least, that's what it feels like right now.
You know, I was actually pretty good at the whole "Magic Eye" thing. I could almost always do it and see the image, and it never really bothered me. But trying to do it with a moving image - much less control one is an exercise in brain pain that I can't take much of.
Try it out yourself, if you dare.
