Happy Birthday Alexander Calder!

From our website:

Calder’s interest in movement appeared early in his figurative wire sculptures, which have a playful, mechanical sensibility akin to wind-up toys. Some of his subsequent abstract sculptures are operated with cranks and pulleys, but his real breakthrough came with his invention of hanging sculpture. Calder’s mobiles consist of abstract shapes connected by wires and move freely with the air currents in a room.
