The WowWee Rovio is a cool Wi-Fi enabled robotic webcam. I like to call Rovio a remote-controlled VoIP webcam sentry robot. 
The Rovio is pretty futuristic looking. It looks like it belongs on some sci-fi TV show or movie. Reminds me of some vehicle I saw on Terminator 2. The Rovio can move in any direction and can be controlled remotely. Simply view and interact with Rovio's environment through its streaming video and audio from its built in camera using a browser. You can even control the Rovio from an iPhone and the Nintendo DS.
