In Japan, nerds control girls with joysticks

For some of you, like this guy (look at his face!), this is a dream come true, no questions asked. The rest will be wondering what the hell is going on here. See, that bicycle helmet affixed with what looks like a robotic crab is a not so subtle, ear tugging navigational device that could ultimately benefit the sight-impaired or anyone, really -- it pulls on the left ear to direct the wearer to the left, on the right to go right. Simple. Granted, it looks ridiculous now, but imagine it miniaturized under a tin-foil helmet and communicating with a hands- and eyes-free GPS navigational system. You've just seen the future, how does it feel?
