Probably one of the coolest things I've seen recently... okay, two of the coolest things I've seen recently, both from the Fluid Dynamics Laboratory at MIT. One of them is a "robotic" water strider, and the other is a robotic snail. The water strider is wind-up mechanical, but really, and truly novel.

Fluids are truly underrated... it's great to see roboticists fiddling around with this stuff instead of all following Rodney Brooks like blind disciples. Don't get me wrong, I think Brooks has some cool ideas, but I think he's singlehandedly responsible for killing any momentum towards true, generalized artificial intelligence at one of the foremost institutions in the nation. So sad.
