This little wind-up bot from Brazilian toymaker and environmental activist Chico Bicalho does a spastic jitter when you let it go. In fact, all Bicalho's creations are goofy, jumpy critters that are pretty much the opposite of what you'd expect from a robot. They shoot sparks, wobble lopsidedly on their wheels, and hurl themselves upsidown if given a chance. I'm lucky enough to own one, called a Sparklz, that is a wobbly fire-squirter. Check out some videos of Sparklz and its crazy bot friends below.

It's Friday morning, and even the bots are dancing to celebrate. Here's another one, called Cosmo Jetz. And here's Cranky.
