Some of these are playful: West's 2012 work with Marina Faust, Talk Without Words (Christopher Wool) for example, a large mohair ball
hung on a cord
over a table, with visitors invited to knock the ball to each other with their
foreheads; or the artist's venture with Rudolf Polansky, Siesta (2003), a couch covered with a throw printed with the repeated motif of an ape's sphincter.
