Circuit Scribe circuit-drawing pen is just plain cool

I came across the Circuit Scribe on Kickstarter earlier today and it is awesome.


It's a pen that uses an instantly-drying conductive ink to draw circuits on plain paper. This should allow you to teach or prototype circuits in seconds and I can't wait to get my hands on one. I've already donated to their Kickstarter page and reserved a few pens for myself.
