From the TED (Technology, Entertainment , Design) site:

This demo — from Pattie Maes’ lab at MIT, spearheaded by Pranav Mistry — was the buzz of TED. It’s a wearable device with a projector that paves the way for profound interaction with our environment.

Pranav Mistry is the genius behind Sixth Sense, a wearable device that enables new interactions between the real world and the world of data.

Take a look at TED, too.  Efforts began in 1984 to share earth-shaking ideas at a conference in Long Beach, CA.  The best talks and performances are  freely available to view.  One can subscribe to the TED series.
