Experience Strandbeest: The Dream Machines of Theo Jansen at the Exploratorium from May 27 to September 5, 2016. Jansen’'s strandbeests—“, "beach animals”" in Dutch—, are enormous, self-propelling kinetic creations. Constructed largely of PVC tubing and other hardware store materials, strandbeests are mesmerizing in their motions and eerily lifelike. Equipped with sensory organs and ever-evolving survival strategies, they walk a wandering, wind-blown line between art and engineering, mechanics and biology. Physicist-turned-artist Jansen has been creating strandbeests since 1990. Iteratively designed and intricately assembled, Jansen’'s self-propelled creatures have evolved over the years, becoming increasingly complex and lifelike, with specialized adaptations to help them survive in their seaside environment.
