Your cat’s ears broadcast her emotions to the world, telling you whether she is angry, happy or tired. Inspired by our feline friends, Necomimi is a kind of “neurowear”, a headset with ears that move back and forth as your moods change. It has to be seen to be believed (check it out on Youtube). Launched in the U.S. in July by the Japanese company Neurowear, you can now talk cat-to-cat with your favourite kitty, but alas, purring is not included.
