With the fusion of art and engineering, Theo Jansen builds some amazing sculptures that literally walk on their own. 

 "Since 1990 I have been occupied creating new forms of life.

Not pollen or seeds but plastic yellow tubes are used as the basic material of this new nature. I make skeletons that are able to walk on the wind, so they don’t have to eat.

Over time, these skeletons have become increasingly better at surviving the elements such as storms and water and eventually I want to put these animals out in herds on the beaches, so they will live their own lives." 

-A quote taken from his official website, strandbeest.com.  His site is quite interesting by-the-way, complete with a live web cam of his laboratory in the Netherlands. 

Theo Jansen was also featured on TED in 2007.  The "creatures on the beach" portion of the video is rad.
