Would you dare wear a tail out? One that wags according to your mood? This Kickstarter project is for a device called Tailly.

Using sensors built into Tailly’s belt, the device will be able to react to your heart rate and respond accordingly.

“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,” says the project’s Kickstarter page, “When you wear Tailly, you’ll radiate cuteness and happiness!”
