What happened
Air Theremin is a browser-based instrument you play by waving both hands at a webcam or tilting a phone's gyroscope, with hand spread controlling volume, hand height controlling pitch, and gestures for vibrato and tone. It also falls back to mouse input and runs on a plain laptop webcam. It was created by Pavel Gurov and is based on theremin.site.
Why it matters
It's a compact, working demo of in-browser hand tracking and device gyro APIs without plugins or installs—useful as a reference if you're building gesture-controlled UIs or webcam-based interactions, but there's no code, library, or API exposed here to reuse directly.
Discussion angle
What it takes to ship a zero-install webcam hand-tracking experience in the browser today, and whether this kind of gesture input is viable for real product UX beyond novelty instruments.
