Dutch artist Theo Jansen builds skeletal creatures out of PVC tubing that walk along the beach powered only by wind, and this short film follows them in motion on the Dutch coast. Jansen talks through his process as the camera lingers on the mechanics: hundreds of legs cycling in sequence, sails and crank systems converting gusts into steady, animal-like gait. He describes the creatures, which he calls Strandbeest, as an evolving species, each generation refined or scrapped based on how well it survives wind and sand, with some models storing air in plastic bottles so they can keep moving after the wind dies. The tone stays close to Jansen's own framing of the work as artificial life rather than sculpture, though the film lets the machines' odd, lurching walk make that case visually more than any single line of narration does. It is a compact look at a project that treats engineering as a kind of biology, with beach terrain standing in for natural selection.
