Good Vibrations: Future Skeleton Keys and Hard-Working Tattoos

AT&T Labs is working on a system in which your cell phone or wristwatch would create a unique vibration that travels through your bones, reaching a receiver in a door handle and automatically unlocking the door. (The vibration can’t be felt but would be audible in a silent room.)

On a related but not as new note: Nokia has filed for a patent on a magnetic vibrating tattoo. According to the patent, the tattoo (really more of a skin graft) could be set so that each time you get a call or email, you would feel a different vibration pattern.
