Cave Hands
A shared wall of hand stencils, like the ones people left in caves by blowing pigment around a hand pressed to the
rock.
Scroll down to find a spot. Hold your hand up to the camera, in any pose, and keep it still until the ring
closes. It is then sprayed onto the wall.
The camera picture never leaves your device. A small model in your browser finds your hand, and only the finished
stencil is saved.
