Japan's Latest Rockstar Is a 3D Hologram

kkleiner writes "Hatsune Miku is a Japanese pop diva who's just started to play massive stadium concerts to sold out crowds. Her hair is blue, she dresses like Sailor Moon, and she'll only appear in concerts via a 3D 'hologram.' Oh, and did I forget to mention that she's completely fictional? Created by Crypton Future Media, Hatsune Miku and her virtual colleagues have gone on limited tours in Japan."
