In conjuntion with American website, Aniboom.com, Radiohead are running a In Rainbows Music Video Contest, to be judged by the band themselves. The basic premise is, unsurprisingly, to make a music video for In Rainbows. There is $10k up for grabs too (sounds bloody cheap considering they made squillions on the album)...

Nine Inch Nails are doing something remarkably similar with their Ghosts I-IV album that was released recently, asking fans to make videos for any tracks they please. Only they don't have big shiny cash prizes on offer, merely the nodding approval of their Gothic Overlord, Trent Reznor.
