Joshua McGee created Tile Array, an application that makes a mosaic out of any image. The tiles are images from Wikimedia Commons, but only square images are used, so most of them are album covers. You can upload your own pictures and make them mosaics, just like I did with this familiar robot. At the Tile Array gallery, you can enlarge the tiles in the Neatoramabot to see the images it is constructed from. I also did a picture of myself, and was tickled to find some of my favorite albums among the "pixels." -via Metafilter
