Thomas Ruff’s nudes are not what one generally expects from a serious artist. He starts with the crass, hardcore images of internet porn, then molds and blurrs colors and shapes, creating works which retain the raw sexuality of the ‘net, but with little of its horrifying starkness. It’s a dicey art form, Ruff admits, but his work is starting to win admirers all over the world, and inherent in his success is the question of where the lines between art and reality lie these days.
