This is quite clever, though I'd worry about it damaging the screen with use. That you can use two for dual-stick games is also ingenious. That said, this is really just a workaround for the fact that most smart-phone/tablet game developers are trying to write games that depend on the wrong input mechanic. I think this is a big part of the reason Angry Birds is so successful: the game's input mechanic works with touch screens, not around/against them. - Laurence Gonsalves
