Say hello to Rolly, the dancing egg. This Sony MP3 player can spin around with sensors that allow volume control when turned clockwise or counterclockwise or switch music with a push or pull. Weighing only 11 oz., it holds 1 GB of flash memory and built-in speakers. Bluetooth capable, it is programmable with software that will analyze music and then create choreography for the little bugger. It also doubles as an alarm clock. Rolly can keep going for about five hours before needing a recharge, and will hold 100 to 600 tunes, depending on the complexity of its dance steps. Only available at this point in Japan, its MSRP is ~$354.00.
