Theo Jansen is a physicist by training who has put his knowledge at the service of art. Since 1990, it focuses on the realization of works related to the animal world and especially the assembly of large skeletons made of plastic tubes that simply moving through the wind. The artist likes to think that his designs are alive and he is even considering letting them loose on the beach for them to take their independence.
