Take wearable computing and mash it up with natural surface interface technologies and sprinkle in some Minority Report movie magic...then you get the coolest piece of tech I have ever seen; SIXTHSENSE
"SixthSense is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information... SixthSense attempts to free information from its confines by seamlessly integrating it with reality, and thus making the entire world your computer."
Pattie Maes heads up the Fluid Interfaces Group at MIT labs. Pranav Mistry is the student lead for the project and a pretty interesting guy... Their projects are really ground breaking but this Sixthsense project is jawdropping...I want one ;-)
