Explore what can happen when art and technology collide at this three-day festival of performances, installations and discussions. You’ll see creative uses of new media, such as musicians from New York and Manchester improvising together onstage via Web feed, a wireless sensor glove that translates movement into sounds and visuals, and a piano whose keys trigger video projections of people singing the “played” musical notes.
