Painter and sculptor Keith Tyson, whose playful work is inspired by scientific theories and often ponders the role of computers, won Britain's prestigious Turner Prize for visual art.
Among Tyson's works is a computer that generates random artistic ideas. It prompted him to create lead casts of every item on a KFC menu.
Tyson, 33, used his acceptance speech to praise his fellow contestants and wish his grandmother happy birthday. "She has undying faith in me but has no comprehension of what I do."
