The Grippity is a crazy-looking device that's designed to completely change the way you type. You hold it in your hands and type from the back, as you're able to see through the keyboard to your fingers behind it. There are controls for your thumbs up top as well, allowing you to fully control a computer using a grip reminiscent of a video game controller.
It's certainly an interesting idea, although one that would take a very long time to get good at using. Think of how long it took you to learn how to type on a regular QWERTY keyboard, and now envision starting over from scratch. No thanks. In any case, the Grippity should be out in about six months for $100 if you want to give it a shot.
