The Disney research lab in Pittsburgh released a cool demo video showing how any surface can be converted into a touch sensor.  One of the coolest applications would be to use your skin to control an iPhone.  Your body becomes the buttons…touch your palm with one finger for one action, two fingers for something different, touch the wrist for another action, you get the idea.  Exciting possibilities here, check out the video:

If you’re more the DIY type, check out the video below that shows someone making their own version of this touch sensor.  You can find instructions and details here.
