From the README

Ink runs from your fingertips into water, over your own webcam picture, with the hand tracking drawn on top.

**Try it: (allow the camera and the microphone). No camera at hand? The same page with ?demo=1&bg=video plays a loop with two synthetic hands, which is what the animation above shows.

Each hand carries its own pigment and the two mix where they meet. The overlay is a live debug view of the tracker: every number on it is a value the ink is driven by. One key records the result to a video file, either 16:9 or already framed for a vertical reel.
