Questions on HoloPac

Why is the first major appearance of the technology recreating a personality who already has so much available content? Why not someone who has never materialized to the popular imagination in a moving visual form?  (Jesus, Lincoln, Bethoven)Who holds the rights to someone's likeness after they pass? Did 2Pac's family have any legal authority over his re-creation? Will his copyright holders get any royalties from the performance?Was this only possible with 2pac because of the pre-recorded vocals?  Would the performance have been interesting if live performers weren't also collaborating?Who is writing tweets for @HologramTupac? Was the account conceived before the show? The jokes are brilliant.Credit to the Atlantic for making me think beyond "wow, that's cool."http://www.theatlantic.com/entertainment/archive/2012/04/hologram-tupac-was-inevitable/255990/#[youtube=http://www.youtube.com/watch?v=l9yFYmboERs]
