Who can get enough of graceful mechanical creatures created by Dutch artist, Theo Jansen? His 'Strandbeests' are wind powered walking creatures part art, part engineering, and certainly inspired by nature.
If you find these creations as fascinating as I do, you may want to study one (a small one) up close and personal. The good news is, you can. The Japanese company Gakken offers a number of working models of Jansens's kinetic creatures.
