Jeffrey Burns' The Piano of Light is a computer-driven visual music system created to play Scriabin's Prometheus and other pieces of visual music.
The press quoted on the page summarize the project pretty well: "With four contemporary works and the Seventh Sonata of Scriabin, together with a projection screen filled with graphics and the lively play of 60 spotlights onto an artificial 'sky' hung from Podewil's theater ceiling, the first performance on this 'instrument' became a rapturous multimedia event."- Neue Musikzeitung
Scott Snibe has some movies for webbrowser: "I was searching for a way to make a hard-edged abstraction like Fischinger's by using my body directly as Lye did. In an epiphany one evening staring at the computer, I realized that the cursor was the most interesting object on the screen. Here was the only place that my body, through the mouse, came into the computer. Based on this understanding, I created Motion Sketch, which attaches the movements of ones hand to the movements of abstract forms. These forms exist in a short one-second loop. The temporal complexity comes from the continuous layering of these forms, creating a rich motion painting."
