iDance Wireless Dance System

Video games are always blamed for making kids fat. iDance probably doesn't do that. It's a frenetic, multiplayer "exergame" similar to the popular Dance Dance Revolution games. Users dance on wireless-enabled platforms in response to scrolling indicators on a monitor where they follow along. Up to 32 platforms can be used at the same time for a group workout.
