Ghost Hand

[Download the film](docs/videos/ghost-hand-film.mp4) ([captions](docs/videos/ghost-hand-film.vtt)).+ Ghost Hand is a small battery gadget you set on the counter beside a sink with an automatic faucet. It aims infrared light at the faucet's sensor so the water keeps running while you wash your hair, do the dishes or fill a jug, then hands the faucet back when you are done. It learns each faucet's safety
