Yet another unusual video! Kinetic sculptor and artist Theo Jansen builds 'strandbeests' from yellow plastic tubing that is readily available in his native Holland. The graceful creatures evolve over time as Theo adapts their designs to harness the wind more efficiently. They are powered only by the wind and even store some of the wind's energy in plastic bottle 'stomachs' to be used when there is no wind.
