From the README

Pick a classical masterpiece. Mime it at your webcam. Every stroke of your hands plays the next beat — so if you slow down, the music slows down with you. Play hard for forte, soft for piano, lift your hands to hold the pedal. There is a cat, and it has opinions.

It is a toy. Nobody wins.

No camera? SPACE is a keystroke and everything else still works.

The camera is read by a hand landmarker — twenty-one points per hand, both hands, on every frame the camera produces.
