I was watching the episode of Good Mythical Morning where they explain how the Tupac hologram works.(If you're a fan of GMM please comment fellow mythical beast)
While watching this I found out that in Japan you can actually go to a live vocaloid concert and see a hologram of Hatsune Miku sing and dance on stage.

Rhett and Link ( the hosts of GMM ) said that they didn't think this kind of thing would be popular in the U.S. But I think they probably said that because they aren't fans of anime or manga and they probably don't even know what vocaloid is.
Or maybe I'm really the only one who thinks this vocaloid concert is an awesome idea.
I would pay to see Hatsune Miku in a concert even though I don't speak Japanese and would have no idea what she's saying.
It just looks like so much fun to me
