Sony announces that their funky music gadget Rolly is now available in the United States. Sony introduced the Sony Rolly in Japan in September 2007.

The palm-sized, egg-shaped device rolls and spins like it’s dancing to the music.

With built-in robotic technologies, Rolly is designed to move its small arms, shoulders and wheels—six moving parts—to the beat of the music. With about 700 colors in its repertoire, lighting adds to the impact of the motion.
