Tailly: a heart-rate-controlled costume tail, on Indiegogo

Elix sez, "Tailly is the invention of Shota Ishiwatari, the Japanese maker/inventor that designed and built the prototypes for the emotion-displaying Necomimi cat ears by NeuroSky. He's invented a tail that monitors your heart rate and reacts accordingly: A slow, lazy swish when you're relaxed, a brisk wag when you're excited, and so on. The goal is to deliver the goods (if successful) in September. It's down to the last three days, and it's struggling. It's only raised about 30% of its goal, and it could use some happy mutant help. The actual cost for the initial production run is $100,000, but Ishiwatari has negotiated a deal with a trading company to get them to kick in half if he can crowdfund the other half. This is a Kickstarter-style fixed funding campaign, so if he doesn't make the goal, he gets nothing at all."

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.
