I accidentally set my avatar as my wallpaper, then I tiled it just for kicks. Then I got 'up', went cross-eyed for a second cuz I was coughing and it turned into one of those MAGIC EYE things! This is no joke, there's no hidden picture, but the blue parts form 3D ridges! I showed this to a friend and it took his eyes awhile to decipher the effect, but he did see it, and you do not need to be 'up' to see this lol. Please be brave enough to try this and see the effect. The avatar is a picture of a microscopic bacteria nothing special or meant to have such an effect.
