Cat tail sways to your pulse rate

We have seen the Necomimi mind-controlled cat ear headband in the past, so if you happen to already own one of those, then you might want to check out this pulse-controlled cat tail. The tail itself will come covered in hand-knit fur to disguise its robotic roots, and it will be connected to a pulse sensor thanks to an AVR microcontroller. The sensor itself will be attached to a clothespin that is clipped on your ear lobe, where your body's pulse rate will then be sent over to the tail.
