Once again, reality beats fiction: If your name is Jerry Jalava, the USB finger is more than just a concept. It's the real thing embedded in your own hand, carrying a Billix Linux distribution.
Jerry had an accident while biking, losing his finger. He got an artificial finger made of silicon, and instead of just giving it logical sexual uses, he decided to make it even more useful and embed a 2GB USB drive inside. The result is equally as gross as is fascinating. [Flickr via Bergie]
