Seiko Epson's even better flying microbot

Seiko Epson's introduced a new, slightly improved version of their world's smallest flying robot, which is basically a wirelessly-controlled helicopter with two small ultrasonic motors (and we're not entirely sure what makes this a robot and not a radio-controlled toy, but Seiko Epson seems plenty excited about it so we won't spoil their fun). If you happen to be in Tokyo around the end of this month (Gareth, we expect photos), they'll be showing it off at a fair at the Tokyo International Forum.
