Theodorus Gerardus Jozef “Theo” Jansen (born March 14, 1948) is a Dutch artist.
In 1990, he began building large mechanisms out of PVC that are able to move on their own and, collectively, are entitled, Strandbeest. The kinetic sculptures appear to walk. His animated works are intended to be a fusion of art and engineering. He has said that “The walls between art and engineering exist only in our minds.” He strives to equip his creations with their own artificial intelligence so they may avoid obstacles such as the sea, by changing course when detected.
