Man in Boat is actually one of the less clever lolvants. For example. And also. But what makes it truly awesome is the commentary that goes along with the images. Such as:
Acconci was a poet. Then he masturbated under a ramp in a gallery where people were encouraged to walk around said ramp. He also cooed sexual fantasies at people using a microphone. People agree this is a brilliant piece because it took conceptual art to it's logical conclusion: replacing figurative masturbation with the real thing. 1972.
