I was really touched by this technology by Rationalcraft on Winscape.  The fact that a user is connected to the screen with there mobile device is definitely where things are going in the world of cross-media.   This example is only for the purpose of Augmented Reality of landscapes, but think of this kind of TV display and the ability to zoom-in and out of a sporting event like you were there live.  Almost like what we can do with maps, but with live streaming.  Very cool stuff.
