Theo Jansen's Wind-powered "Animals"

Theo Jansen is a Dutch kinetic sculptor who creates wind-powered "animals". On his website he states that

I make skeletons that are able to walk on the wind, so they don’t have to eat.

Here is a video with footage of his sculptures moving around:

As a side note: my girlfriend found this while using http://www.stumbleupon.com. If you haven't heard of or used StumbleUpon, spend a few minutes with it. It randomly (well, almost randomly) loads webpages and you vote whether it is of interest to you or not. Eventually it will show you websites that are more relevant to your personal interests. There is quite a bit of uninteresting content that will show up but every once in a while a great art or art-related website will appear.
