So this is pretty cool.

Vocaloids are one of those weird japanese things that I've always been sort of tangentially aware of but never really cared about, though they are pretty neat. I have friends who are really into this stuff, know all the names and histories of the different characters, but I never really cared. They're computer programs. If you have enough time on your hands, you download them and make them sing things. It's fun to listen to, but it's not really something I really care to get involved with, you know?

But I thought this was a really cool video.
