It can be tough playing games on a tablet, since you can't hold 'em up comfortably like a controller or a phone. Silicon Valley startup HandScape believes their iPhone and iPad "HandyCase" is the answer to that problem. HandyCase might look just like any other protective shell, you see, but it actually adds touch capability to the back of your device. Plus, it animates your fingers as you move them from behind, making the phone or tablet seem transparent. You can even choose what kind of fingers you see on screen: the ordinary/boring kind, robotic digits or x-ray hands.
