The Tate Modern is hosting a major exhibition on Nam June Paik, the innovative artist known for his pioneering use of TV and video. Over 200 of his pieces from his 50 year career will be on show, including robots made from old television screens and room-sized installations like Sistine Chapel 1993. The exhibition will also explore his collaborative, cross-discipline works with the likes of cellist Charlotte Moorman, John Cage, Merce Cunningham and Joseph Beuys.
