The visuals in a zone were affected by the movements of the player, the beat of the music and the section of the music that is being selected by the EJ (the experience jockey). Each of the six graphics input zones were made of the following ingredients:

One person from the crowd was in each zone in front of some input devices that they could control.

A set of input devices through which the player controls graphics and sound. (A "Tweak" zone had four light beams the person could break, plus a sensor at the player's hips to measure their wiggle.)


Houdini animation software on a Silicon Graphics Octane workstation generates the realtime 3D graphics.

A large rear-projection screen displays the graphics from Houdini.


PiOS controls the music which is generated by synthesizers, samplers and modified through effects boxes.

Local speakers play sound effects and musical samples that the player is controlling.
