Air Theremin – a browser theremin you play by waving at your webcam

Air Theremin is a browser-based musical instrument that lets users play a theremin by waving their hands at a webcam or tilting a phone. Players control volume by spreading or bringing their hands together, adjust pitch by raising their hands, and can add effects like vibrato and reverb using various hand gestures. The application offers multiple control modes including hand tracking, gyroscope tilt, and mouse input for users without cameras or motion sensors.
