Description

The piano player tirelessly hits the keys - as long as the sand lasts.

The piano player tirelessly hits the keys - as long as the sand lasts.

The mecanical sculpture is powered by a sand motor. From a hopper in the upper part of the model sand trickles on a lever like in an hour glass. Under the weight  of the sand the lever comes down - at the same time the forelegs are going up. Forelegs and lever are connected by a toothpick as an axle. The sand gllides down from the sloping lever and it raises up again - the piano plaers hands are falling down on the keys.
