(for those wondering: this is about using a webcam to detect hand movements or facial expressions and translate them to MIDI)
I haven’t tried it yet, but I had a look and it looks fun. Thanks for sharing this!
Worth to mention: it’s open source (relevant for anything capturing your face, I guess): https://github.com/kitchWWW/sounds.pink but it’s definitely not ready. The developer says “currently we are in ‘make it work’ mode. (meaning things are still quite broken)” and is looking for contributions/collaborators.
