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.
More recently, Cutup have started other projects, such as replacing small bus-shelter advertisements with a drilled sheet of wood. The illuminating back lights that turn on at dusk reveal an image, as the many holes light up against the dark background.
Although they mainly deal with art on the street, the group have also created installations, including setting 96 different alarm clocks one a minute apart and sound installations, made up of 94 speakers, mini disks and circuit boards.
