Theo Jansen, a Dutch artist and kinetic scultpor, born in March 14, 1948, builds large works which resemble skeletons of animals and are able to walk using the wind on the beaches. His animated works are a fusion of art and engineering.
8 links per leg
120 degrees of crank rotation per stride.

“The walls between art and engineering exist only in our minds.” Theo Jansen
