Theremin 2.0

This site turns your device into a virtual theremin using your front camera and on-device hand tracking (MediaPipe). No video ever leaves your device.

Left hand: pitch (higher on screen → higher note).
Right hand: volume (higher on screen → louder).
Audio starts only after your tap (mobile browser rules).

Why camera access? Your hand landmarks are computed locally to control sound. We don’t record or upload video.
