Theo Jansen

Is a Dutch artist who studied physics and now builds amazing structures that move and "walk" by using the power of the wind.

There are some videos of this amazing creation here

These skeletal creatures move up and along the beach. He creates these things to basically have a mind of their own that can sense obstacles in its way and avoid them. Also some can store the wind to continue moving even if there is none while others have devices that can anchor themselves to the ground in order to avoid being blown over.

Jansen quit Physics to become a painter and then made a UFO at one point that flew across Paris. And then later developed an amazing painting machine
