There's some rather lovely work here by Marco Triverio, an interaction designer at IDEO, playing around with (and disrupting) the asynchronous nature of much non-verbal communication over mobile devices. Feel Me experiments with different ways of creating a 'sweet, playful connection with the person on the other side'. I'm quite taken with some of the ideas here, particularly the thought about creating more real-time physical connections through digital means, and the far more inventive ways than we have at our disposal right now to express feeling through non-verbal gestures over digital devices. It certainly makes things like emoticons look awfully clunky.
