Is this idea possible?

Is it possible to create a brick that's basically used for spectating?

For example, in a lobby after somebody has died, there is a TV on the wall. That TV is display people in the games movements, basically. Say it was in The Mad Murderer, the TV on the wall would basically just be a camera over the murderers head that follows them, like a spectate thing. I just think it would be cool to have this on a TV sort of thing rather than having the traditional spectate gui.

NOTE: I am not requesting anybody to make this for me. I'm simply asking if this is possible, and any tips on how to go about this, if it is. I've tried searching for information about it, but I found nothing.
