Sony revealed an egg-shaped digital music player named Rolly (picture below) at the end of 2007, but I haven’t had the chance to see it until last weekend. It plays MP3 and AAC music files and supports direct music streaming over a Bluetooth connection. And it is able to dance.

The Rolly is more than an ordinary music player. Thus, it is motion-controlled robot with a bunch of sensors, color lights, and two flapping wings. It uses two wheels that surround the body to roll, wiggle, and spin. In vertical position the wheels can be used to change songs and adjust volume. The Rolly creates motion automatically by analyzing the music, so it can dance to any song. Also, there is a possibility of creating new motions or customizing exiting ones using PC software. You can see the Rolly’s dance in the video below. It is amazing how the sound and motion are synchronized.
