0arpoky 9 years ago There is an old toy I got years ago for Christmas called Zoundz. Zoundz was essentially a music mixer with lights that responded to the volume, speed, and rhythm of a group of pawns that are set on three sensors inside the casing. Each pawn had a different style of sound, like soft, cosmic, funky, and chimes. There was also a white cube pawn that could have sounds recorded to it. So there were 7 pawns, and each pawn had three loops loaded on it. You could move the pawns to other sensors on the main unit to achieve the different loops. There was another option, as well, you could plug an MP3 player into the main unit. When this is done the pawns will not work as long as the player is plugged in, and the main unit will create a light show to go along with the unit. It may be possible that this man took apart a crapload of Zoundz units and placed them around his clothing. As he plugged in his iPhone, the music he played made the units react to the sound, and create a light show. THIS IS ONLY A SPECULATION!!!!!
