The Xbox 360 Kinect has a rather neat voice-control feature. It lets you switch TV channels, pause games, and do just about everything you'd normally do with a remote control. Including pissing off your friends.
Our mischievous pals at Kotaku noticed that the Kinect's voice-control feature doesn't appear to differentiate between voices. This means that it'll take a command from any person within microphone range.
It also means that you can stroll through your friend's living room and mutter "Xbox...pause" during a critical moment. [Kotaku]
