What is really exciting about this is that it could potentially be used as an ad hoc surface generator. A basic idea would be to have physical keys on the variety of piano apps available for iOS. An extreme example would be having terrain pop up of the screen in games like "the bard's tale", providing tactile knowledge of the game levels. There isn't much information on the actual implementation on the website, but if you could make the surface depress-able or not depending on the context requirement, then the variety of applications is endless: Think of the blind, being able to use tablets to read with Braille(non depress-able), or the piano idea from above( depress-able).
