The creations of Dutch artist Theo Jansen are like nothing you’ve ever seen before. His “kinetic sculptures” called “Strandbeests” utilize the wind to move and walk on their own.
According to the BBC:
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.
