Below is a must see video, but for now... the introduction!
Theo Janson is a kinetic sculpter and builder in Holland. He has used PVC piping to create very life-like structures that harness the wind to move. These creations look like bugs crawling up and down the sand dunes. These things are so realistic that it is almost hard to believe! They seem to effortlessly move around in a strange insect-like way. I know if I had a beach, I would want one. Hell, I want one anyway!
Make sure to watch this video all the way through. I am absolutely astonished!
