This animation footage is from a game called Hatsune Miku: Project Diva. Project Diva is a Japanese based game and only two languages are use, Japanese and English. If you are interested in the game, you can buy it from a range of websites though I cannot recommend any (The game is only available on PS3 or PSP). If you would like more information on the game this website is most helpful: http://miku.sega.jp/ Please note this is not my work.
