Check out the R2D2 robot video, scroll down,
I use the Arduino UNO and I have access to a 3-D printer (incredible what can be done with these printers!)
THe mashable example is silly, but this technology is going to break out all over the tech-savvy world.
I implanted a camera, small arduino computer, sound receiver in a La-La-Loospsie head... senors connect to my lap-top.
This is SPY stuff to the max!
