Thought this was something super and a great way to engage people in creating music and being part of it.
Well done Virgin Mobile.
Exert from Digital Buzz:
An Echo Temple? Yep, Kyocera teamed up with Virgin to create this amazing installation at the Virgin Mobile FreeFest, allowing users to play virtual instruments and create music by moving their body in front of motion-tracking cameras.
But it wasn’t just about body movement, you could use fans that had special (rather weird) symbols printed on them to help control the volume, pitch and unique audio effects as the cameras tracked them. The Echo Temple included six monolithic speaker towers for the party goers to play with, all circling around a huge subwoofer station. Very very cool. And with over 50,000 people at the event, the Echo Temple eventually became its own parry!
The installation’s technology combined Ableton Live, Cycling74 Max and ReacTIVision. Cameras in each tower were fed into embedded systems running a custom build of ReacTIVision which tracked both symbols as well as body movement and camera activity. This was all sent to MaxMSP, which in turn was used to transform the raw input into meaningful musical control information for Live.
