Banpresto, a subsidiary company of Bandai has created a mini shaking hip device that is powered by USB. Even though this device is the exact opposite of sexy, it is being offered in four different colors in Japan starting in June. I guess that it was entertaining enough for people to want variety. They cost about $15.
