Sixth-sense: where the information superhighway meets the streets
This is amazingly Cool, and definitely with a capital C. Pattie Maes and Pranav Mistry from MIT showcase Sixth Sense in this TED talk (video below). Sixth Sense is an augmented reality device that takes information from the net that is contextually relevant to what is currently in front of you, and seamlessly integrates it in to your viewing space.
The device works using a small camera to track movement and a projector to display information on any surface you present (from the wall to your hand).
Imagine picking up a book in the book store and having the Amazon.com or Goodreads.com reader rating projected on its cover (and reviews projected on the blank inner sleeve), a clock projected on to your wrist or a picture taken by making a square around your subject of choice with your hands. All of these are demonstrated in the below video.
And the best bit? Sixth Sense is going open source. I am so going to be one of the first in line for this.

Chris is a shining example of how, in a world where abortion is not as easily obtained as a leg of fried chicken, an ounce of prevention can be worth more than its weight in gold. He is currently completing a PhD in Bioinformatics which he hopes may one day help him get out of a speeding ticket.
