Coffin you can make a miku/vocaloid concert in your house bro.

That sounds pretty awesome actually. Let me know how it goes.
The software it's self just creates the songs, as far as the actual dance I believe he's actually creating them, or ripping the dance / models from project diva.
Which is a psp video game of vocaloid.

I found a video of how to get the animation models. I haven't watched it yet though.
