Check out the beautiful construction and wonderful motion of this walking figure by Mark Galt.
A short bio from the Maker Faire web site:
Mark Galt is a kinetic sculptor who makes mechanical and musical automata in brass, copper, stainless steel, and wood. Forever amused and fascinated by the human figure in motion, most of his work consists of clockwork depictions or exaggerations of the human body or body parts in the acts of dancing, walking, singing, speaking, and otherwise moving about.
