Play a Theremin with Your Bare Hands in the Browser
Air Theremin – a browser theremin you play by waving at your webcam
Air Theremin turns your webcam into a musical instrument: wave both hands to control volume and pitch, lean back to soften the tone, and bring palms together for silence. On phones, tilt the device instead—left-right for volume, forward-back for pitch. No camera or gyro? Use the mouse. Created by Pavel Gurov, based on theremin.site.
SPREAD HANDS = LOUDER · PALMS TOGETHER = SILENCE

I find it a bit suspicious that this exact hand waving data could be used to solve Google's latest reCAPTCHA: https://docs.cloud.google.com/recaptcha/docs/hand-gesture-ve...

I’m going to get pwned one of these days, considering my threshold for giving a random website access to my webcam is apparently mild curiosity and entertainment for 30s.

Funny I built a very similar app just a few days ago. Cool idea!

Funny, I guess this idea is in the air (har har).
I've made a couple things along these lines over the past year. One is a fun, Halloween-themed toy:

The other is a (slightly) more serious exploration of multivariate time signals as a control signal for an instrument. In the latter case, the instrument is learned/inferred from a segment of input audio:

This is a really neat idea! Like others here, I'm not a huge fan of the hyper-dense and dripping-with-ai UI, though.

I made one of these recently! Total vibe-code, but exactly the sort of thing that I'd never get around to without.
Plugged it into Sonic Pi, wired it up to play samples on gestures. Got a nice installation brewing at some point.
