Amazing wind powered robot

From Hank Green at EcoGeek:

This is, by far, one of the coolest things I've seen in a long time. They really are just beautiful and fascinating and, in a way, kinda moving. These magnificent sculptures are powered by the wind and move in beautiful and unexpected ways. They were designed by Dutch artist Theo Jansen who hopes, someday, that his creations can be set loose in the winds of the world to live lives of their own.

I don't know about that, but this video is definitely worth watching.

I would tend to agree with Hank. I am a bit baffled so far what exactly is storing the wind power and providing the motive force for the parts that are all moving. There are a few more videos in the Eco Geek article on their page. Be sure to check them out as well.
