Theo Jansen’s Latest Strandbeest Caterpillar

This is a video of Theo Jansen’s latest Strandbeest: a caterpillar that’s pulled behind another wind-powered mechanical sculpture, inch-worming its way across the sand. Could you imagine if you were enjoying a pleasant beach day and a Strandbeest walked by? That would be wild. Even wilder if it tried to steal your snacks and you had to fight it!
