The e-volo Multicopter made its maiden voyage recently.
Pretty neat concept - a 16-blade electric rotorcraft in which movement about all three axes is controlled by varying the each rotor rpm independently, vice varying blade pitch. In theory, the same maneuverability afforded by a helicopter, but with fewer moving parts and less maintenance requirements.
(Too bad the pilot didn't wear a Sikorsky-esque fedora for his test flight...it would have made up for the video's terrible sound track.)
