Cutup
Cutup is a group of London based artists, whose work mainly revolves around the manipulation of billboard advertisements. Their first works consisted of removing a billboard, painstakingly cutting it up into roughly 4000 small rectangles, each one in essence a pixel, and then reassembling the billboard.
