Pi

Arts and technology collective seeper baked a giant interactive Pi for the 2008 Glastonbury Festival. The filling being the audience. Standing inside the Pi people were tracked by cameras and saw a silhouette of themselves on the walls of the space. As they moved photons, plasmas and other particles radiated from them and were sent flying around the space. Their movement also controlled sound as one of a series of instruments. Scratching a beat, playing a bass or strumming strings made the audience not only the filling but also the players, conductors and composers of their own collective Pi.
