Check out Gest, a Kickstarter project for a device that will let you control your computer or smartphone (iOS and Android) with hand gestures and finger movements. It does this with 15 sensors built into it that track whatever you're doing. You can even touch-type without a keyboard if you have two Gests, and the developers want to usher in the day where a keyboard and mouse is a quaint relic of the past. I'm not so sure I'm ready for that day, but some folks are, because this project zoomed past its US$100,000 funding goal in three days. There are still pledge levels that will let you get one for $149 and a few with two Gests for $249.
