A man lies on a gurney and is hooked up to an ekg, which is hooked up to a laptop which also has a webcam and a video projector. The projector projects real time video onto the stage but keeps track of the location of the man in the led suit. The suit has a photosensor and it's rhythm is modultaed by brightness. Creating a feedback loop as the man in the led suit uses his voice to control the heart rate of the man on the gurney.
