This video brought to you by Tate.org.uk Participatory art was a new concept when the exhibition Bodyspacemotionthings first went on show at the Tate in 1971. Created by the American artist Robert Morris, it consists of a series of beams, weights, platforms, rollers, tunnels and ramps that people can clamber all over. It closed just four days after opening, due to safety concerns over the wildly enthusiastic reaction of the audience. Take a look at this 2009 recreation of the piece and listen as curators Catherine Wood and Kathy Noble talk about Morris's vision of art and participation.
