Have the arm paint you
Stand on the mark in front of the arm. It will look for your face, take one photograph, and show you what it would paint before anything is painted. The photograph is never saved: only the dabs are, and only if you say yes.
Demo mode: no arm and no camera behind this page. Nothing here reaches a machine.
Ready when you are
One press. Somebody at the arm clicks to start it, so nothing moves before a person standing there has seen that you are ready.
Print queue
checkingOne queue for the whole machine. A portrait and a drawing somebody made with a finger are the same kind of job by the time the arm has them, and they are painted in the order they arrived.
Or draw one yourself
Drag a finger across the grid and put the dabs where you want them. Same queue, same two copies.
What happens to the photograph: it is never written down. It exists inside the machine for about a second, becomes 1260 cells of colour, and is gone. Saying no thanks leaves nothing behind, because there was never anything left to leave.
Is this you?
This is what the arm would paint, twice: one sheet for the wall, one for you. The photograph it worked from has already been thrown away.
