The Oppopet is a 3 button wireless optical mouse whose USB receiver takes the shape of different animal tails (“oppo” means “tail” in Japanese). When in use, the mouse takes on a simple discrete shape, and the tail plugs into the computer, extending casually as though a small pet is hiding inside. Comes in 8 variety tail shape with the likes of rabbit, chameleon, dolphin, fox, squirrel, dog, pig and cat (What? No mouse?). Designed by one of my favourite Japanese companies Nendo for Elecom.
