Forget going for a jog while listening to your iPod. Create your own music right at home with the Vinyl Workout.
Designer Theo Watson created the Vinyl Workout for the inaugural Rotterdam Electronic Music Festival. The Vinyl Workout is an interactive workout that turns your floor into a digital record player. By projecting a large record player on the floor that is big enough to walk on, the user can control it by running around on the surface. The system responds to the pace and direction that the runner is going and slow down when you walk around slowly. The record plays backwards or rewinds when you move in the opposite direction.
