Virtual Graphic used on NBC Nightly News

I was surprised last night while viewing NBC Nightly News to hear Brian Williams refer to a new on-screen graphic introducing the next segment as a, "virtual graphic". The graphic appeared 3 dimensional and moved in real space, tracking with the camera and the walking correspondent. I haven't been watching the national network news broadcasts lately, so I'm not sure if this is a first, or a growing trend. I wonder if this technology is an offspin of Tobey McElroy's Georgia Tech Grad project (http://nwn.blogs.com/nwn/2008/01/georgia-tech-gr.html).
