Smartphone Controlled Light-up Ball, Sphero, is Ready to Roll

We first saw Sphero, the smartphone-controlled robotic ball, at last year's CES--but it was just a prototype then. Now it's a product that retails for $129 and has five available free apps with more--both free and paid--apps in the works.

Sphero isn't terribly useful or productive. It's about the size of a baseball and it has a multi-color light inside it. You can control it using apps on your iOS or Android device--you can make it roll around, speed up, slow down, and change color. You can also play games with it, such as "golf," or "driving," using the golf and driving apps. There are a couple of other games, including a "draw and drive" game that lets you draw a path for the Sphero to follow.
