Type Addicted is a typography book, often used by designers and graphic artists. Aside all this, probably it became popular just because of its front cover. Up-close the cover is an unassuming pattern of black and white triangles, but when you try and view the cover from a few feet back, the title of the book comes into focus. You can see the photo of this posted below. Each of these methods will help seeing the illusion: narrow your eyes and relax them, go slightly cross-eyed, and/or simply move few feet away from your monitor. Still, the best method for seeing this is reserved for those of you using our widget – shrinked thumbnail reveals it all, ayeh? If you wish to see more illusions that work on the same principal, you should check Soul wax CD cover, as well as pixelated versions of Marilyn Monroe, Johnny Depp, etc… Does anyone understand the science behind this? Only thing I noticed is that some of the black triangles (that produce letters) are slightly blurred. As always, chime in and let me know what you think about our newest illusion!
