THE IDEA

Make a gesture.
Hear a response.

A webcam instrument that maps hand movement to synthesized vocals, bass, and finger-tap drums, with visuals that follow the performance.

Virtual Theremin brings creative coding, computer vision, and web audio into a single performance space. Hand landmarks drive sound parameters and drum triggers, while the visual scene responds to the same movements. An audio-file player lets a personal track become part of the session.
