Heart-Rate Controlled Robotic Wagging Tails via BoingBoing:
Tailly is not just a toy, nor is it a fashion accessory or a gadget. It is those three items combined, and, since it reacts to the heart beat rate, an extension of the users’ body. Tailly is fun to wear to parties, while out with friends or playing with kids. You could even wear Tailly on a date and express your true feelings through the wagging tail. Even better, your partner could also wear one for the both of you to add a level of subconscious communication between the two of you.
