Orbotix Sphero 2.0 App Controlled Robotic Ball - Retail Packaging - White/Blue
Frankly I'm torn between really cool, and flashy but useless. However if you're not in need of a real robot that will vacuum your house, but something you can tinker with, this is a real nice choice.<br /><br />The basic functionality is simple. This is a gyroscope powered remote controlled ball. There is a mobile app for Android and iOS devices that allows you to remotely move, turn, and jump the ball (yes it can jump by itself). If this was the only functionality I would have called it expensive for that
