Okay, so this is super hard to explain, but just watch the video. It's super cool.
"114.psd Type is a simple typography which I designed once again thanks to Mac OS X. The idea for this type came in when seeing that this operative system memorizes the position of any file or window when you minimize and maximize it. So I created 114 photoshop files (I only used six colors, I played with all possibilites in RGB with the numbers 0 and 255, excepted 0,0,0 and 255,255,255). Then I placed and ordered the files in the right position before minimizing them on the dock. And finally I captured the screen maximizing every file."
