I wasn't expecting an anime character, but more something like in the movie S1m0ne (http://www.imdb.com/title/tt0258153/ http://www.imdb.com/title/tt0258153/). In that movie, the movie/pop star is computer generated but is a "real" person and there actually is a scene with a 3D hologram of her on stage. As someone else mentioned, though I find that to be fascinating, I'm more interested in what they mean exactly by "3D hologram" and how it works.
