@mcourcel it's weird how the snow and sun angle has made this run all day. The little solar panel barely supplies any power. The laser cut wood doesn't run very smoothly. It's kinda warped. And yet it moves.

(The fastest I ever got it to go was by sticking it right in the path of a projector. It was clicking away about once a second.)
