Developed by Colorado-based tech firm Orbotix, Sphero is a self-propelled rolling ball that users remotely control via Bluetooth, using an app on their smartphone. Of all the products on display at CES 2011 in Las Vegas, one that drew a particularly large number of spectators was … a ball. It juices up by sitting in an included induction charger, and works with both iOS and Android devices. Internal LED lights glow through shell, and can be user-adjusted to take on any one of thousands of possible colors. Besides the standard tilt, tap and touch-based directional controls, it also includes an on-screen “boost” button, that gives it a burst of power to climb over things such as carpet edges.
