I remain confused by the Vocoloid sensation. I'm also really amazed by that video - how TF did they project like that in a way that looks good on stage. My goodness. This is one of those "We're in the future now" moments. Though I really can't see wanting to go to a concert that's entirely virtual - I'm waiting to have it in my house like movies I guess.

This just seems so much like tamagotchis - like ... it's not real. Maybe I need to see one singing in English.
