From the McColl Center for Visual Art web site:
Arthur 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.
I've seen some of his work at MIT. It's really cool!
