Martin Creed's work Lights Going On and Off, which features two flashing lights in an empty room, won England's Turner Prize. The prize, which awards £20,000 is for British artists under 50, was presented by Madonna. The choice has resulted in some controversy, as has Madonna's choice of words during the presentation. Courtesy of Metafilter, here's an interview with Creed along with photos of the work in both it's on and off state.
