The great thinkers of the world have long known a secret that we're now happy to disclose: it's not necessity that's the mother invention, but rather laziness . Fortunately, expending a great deal of effort on a project -- simply to perform a task effortlessly -- sometimes brings very cool results. A concept app known as ZuneVoice easily passes muster in this realm, which is used to control Zune software on the PC with only a standard microphone and spoken commands. As you can see in the demo video, its creator, keyboardp, is able to play individual songs, issue commands such a "pause" or "next song", and even display full-screen music videos from YouTube. The developer even crafted an app for his Lumia 800 known as PhoneZune, which serves as a remote control for times when he's away from the box. Neither application is yet publicly available, though feedback is welcome. Next, we're told to expect Kinect integration. Perhaps one day, these gems will see the light of day.
