Over on TED right now (http://www.ted.com/index.php/talks/view/id/245) is a video by a young man named Johnny Lee. He has been using a hacked Nintedo Wii remote and $40 worth of additional kit to create some fantastic interactions: A digital whiteboard running photoshop, a touch screen and (My favourite) a head mounted 3-D viewer that changes the perspective of the onscreen interface to match the user's head position. It could work well to look around a website in 3-D, allowing the user t move their head to look around an object.
It is interesting to see how innovative an enthusiast with a small amount of time and using existing retail technology can be. He has already secured an agreement with EA Sports to use the head mounted 3-D viewer technology in a game for the Nintendo Wii.
I would like to put it out to the wider world to see how any of these interactions could be used by Conchango when developing new IP?
P.S. If you see me in the studio with a soldering iron ripping up the Wii, don't worry I know what I am doing! On a serious note if you have a Wii and would like to try out the interfaces for yourself visit Jonny's website (http://www.cs.cmu.edu/~johnny/projects/wii/).
