We've accomplished many an hour of restful, mugger-prone napping on the subway, but there's always the danger of missing your stop -- a problem we're usually too drowsy to consider at 2am in the morning. Not clever hacker Pyocotan, however. This resourceful fellow has built the Noriko-san sleeping mask for fashion-forward commuters, which broadcasts your destination to fellow passengers on a garish LED display, while you're busy getting some shut-eye underneath the mask -- in the hope that they'll be kind enough to wake you up at the right stop after they've rid you of your iPod and wallet. With a cost of $200 in parts, and considerable impracticality to boot, this device isn't quite ready for the commercial sphere, but that's of little concern to Pyocotan -- he's just busy being awesome. Video is after the break.
