My favorite is Animaris Rhinoceros Transport but the others are amazing too.
Theo Jansen (1948) studied physics at the University of Delft (The Netherlands) from 1968-1975. He left University to become an artist. He painted for the first seven years. In 1980 he built a flying saucer (15 ft flashing lights, beep sounds) that flew over Delft and set the town in commotion. Then he built a light sensitive spray-gun which paints an object on a surface. Since 1986 Theo Jansen has been writing a column for the Volkskrant (national newspaper). Since 1990 he has been working on a new creation: skeletons made of electric-conduits which walk on windpower. These animals have evolved into several generations over the last twelve years. Eventually he wants to put the anima Is out in herds on the beaches, where they live their own lives.
