Back in 2012, before I started doing the smiles, I included a fun video of a self-locomoting art project with the below comment. Someone posted a different video in one of the steampunk groups I belong to, and I remembered the wonder this video provoked. It should have been a smile then, so it will be a smile now.
Enjoy a wander on the stranger side of creation.
The history of Theo Jansen’s Strandbeests, self-mobilizing artificial life made of PVC piping and activated by wind. (Note: Video starts with audio.)
