Theo Jansen (born 1948) is a Dutch artist. In 1990, he began what he is known for today: building large mechanisms out of PVC that are able to move on their own, known as Strandbeest. His animated works are a fusion of art and engineering; in a car company (BMW) television commercial Jansen says: “The walls between art and engineering exist only in our minds.” He strives to equip his creations with their own artificial intelligence so they can avoid obstacles by changing course when one is detected, such as the sea itself.

There is endless potential here, crop planting, watering, harvesting; transportation; and whatever you want to add to this list. And it uses no energy aside from wind, which itself, when needed, could be artificially and sustainably (re)produced. How can such an intelligent species be so dumb over all?
