You might remember the Strandbeests, a set of sculptures/machines that “walk” under their own power due to clever design by their creator, Theo Jansen. The originals were large and hand-made from light wood so they could move easily — but Jansen collaborated with Shapeways to put together a version that they can just print.
It won’t go in wind, of course, but you can see how it moves when pulled by a string in this video. Simultaneously creepy and amazing. They call it Animaris Geneticus Parvus, and you can order one (fully formed! No assembly required!) for around a hundred bucks.
Isn’t it just shocking how cool of a world we live in?
