Arthur Ganson's

Self-described as a cross between a mechanical engineer and a choreographer, Ganson creates contraptions composed of a range of materials from delicate wire to welded steel and concrete. Most are viewer-activated or driven by electric motors. All are driven by a wry sense of humor or a probing philosophical concept.
