While starring at the connection screen, waiting for the server to come up, I realized that the menu screen (and by extension all of minecraft) has stereoscopic qualities i.e. the Magic Eye effect.

I've been playing around with blocks trying to get an idea for an image... This is just a sample with a distorted blob.

Can you see it?

Yes... to me it looks kind of like a peanut.

I did notice this a long time ago

I wonder if notch Intended for this to happen?
