Erwin Wurm,

While arguably not "retinal" art in a conventional sense, the abstractly absurdist sculpture of Austrian artist Erwin Wurm has few explicit points of contact with the rarefied concepts and anti-reification of much contemporary Duchamp scholarship. Wurm's appropriation of the famous Fountain, for example, and his fusion of the urinal with a fanciful representation of its mythical creator, "R. Mutt" himself, is not so much profound as funny. Duchamp also laughed.
