Eye Vapor has recently given technical demonstrations of our large scale concert VJ rig for both the Los Angeles Visual Artists' group and the San Francisco based Bay Area Visual Music Group. We're happy to share our knowledge and hardware. Feel free to contact us about presenting a demo anywhere.
Here's some proof of concept demos for technology we're working with.

Guitar Antihero: Like the game, but with a real guitar and backwards.
The original concert visuals: Sir Isaac Newton's Color Organ (circa 1700).
Guitar Autowhammy: Pitch bending via a wireless inertial sensor.
3D live performance visuals, controlled by a magic wand.
