Cranmer not only babysat theremins at the Ether festival, he also had a piece or two in the show. This one, created with friend Patrick Furness, is an ingenious interactive affair that let attendees produce an ever-changing soundscape by driving radio-controlled cars around on a specially prepared surface. The table has strips of recorded tape pasted on top, and the cars have tape heads on their undersides. The video below shows the labor intensive pasting process in time-lapse. Jump ahead to 2:07 to see the cars racing about.
