Pianist


Size: 10.5 x 9 x 16 cm
Sand motor

Tirelessly the pianist hammers away at the keyboard - as long as the sand runs.


The mechanical sculpture is driven by a "sand motor".  A sand container is located in the upper part of the shelves from which fine sand trickles on a lever, an egg timer is comparable. Under the weight of the sand the lever comes down - and at the same time the arms are going up.  Arms and lever are connected by a cocktail stick as axle. The sand slides down from the sloping lever and the lever raises up again - the pianist's fingers are falling down on the keys.
