this is pretty (and so small)

Courtesy of Scientific American: a robot dragonfly that flies for 3 minutes at about 5m/second and carries an onboard camera. someday soon it will be able to hover like a hummingbird and fly backwards. in the movies, robotic insects that have cameras are usually sort of sinister and creepy and climbing all over things to expose the hero to his nemesis - but this one seems so delicate and elegant that surely it will come solely to its programmer to put it to evil ends... sigh.
