In Seedbed Acconci lay hidden underneath a gallery-wide ramp installed at the Sonnabend Gallery, masturbating while vocalizing into a loudspeaker his fantasies about the visitors walking above him on the ramp. One motivation behind Seedbed was to involve the public in the work's production by creating a situation of reciprocal interchange between artist and viewer."
