If we're being honest (and trust us, we're being honest), Pranav Mistry's Sixth Sense contraption has always baffled us . It's kind of like Sony's Rolly . It looks cool, it sounds rad, but we're fairly certain only 2.49 people actually know and fully comprehend how it works. That said, we're more than jazzed about the possibility of having wearable gesture interfaces gracing every human we come into contact with, and rather than attempting to make his invention "comply with some kind of corporate policy," he's purportedly aiming to release the source code into the wild in order to let "people make their own systems." Nice guy, huh? Sixth Sense creator to release code, wearable gesture interface
