Alan Chatham of Unojoy wrote an Instructable on using pencil drawings as capacitive sensors:

Did you know? You can make pencil drawings reactive to touch for use with your projects! It’s really easy, and gives you a lot of flexibility in making interfaces for whatever microcontroller project you’re making.

    This is cool. I first saw this on the makey-makey site. Really cool to be able to build your own interfaces using pencil and paper!
