Since 1990, Dutch artist Theo Jansen has given life to Strandbeests. They’re made of nothing more than a mass of yellow plastic tubes. But these kinetic sculptures feed off of the wind. They roam the beaches on their own. And they evolve. Soon enough, Jansen says, you will see Strandbeests living in herds, and who knows what the alchemy of art and engineering will bring next.
This clip comes from a BBC production, Nature Knows Best, that aired late last year. You can also catch Jansen introducing his self-propelling beach animals at TED.
