Microsoft just demonstrated an interesting Xbox display accessory at the Samsung CES keynote that apparently fills up the room with images and lights beyond the confines of a television screen. We were shown a video of someone playing Xbox games and making it seem like it's snowing in the room, for example. It's unclear how the technology is being implemented, but we were promised it wasn't just video tricks and was indeed a video of a lab demo. We'll try to suss out the details for more.
