June Song(s) of The Week 4

Really this should be a June six songs of the week, mixed with a Beginner's Guide to Anime post.  This video is a short twelve minute long musical... performed completely by software and animation.  In Japanese pop culture, works like these are often collaborations of animators, composers, arrangers, and so forth.  First, let me explain the voices in this musical (I'll probably make a standalone post on it later):

Vocaloid: Software that emulates singing.  Practically a voice synthesizer.  There are many different models of Vocaloid; English, Japanese, and their own models within those languages.  The most famous of them is the Vocaloid 2 model Hatsune Miku (Alice in the video below).  Other Vocaloid models included in the musical are (in order of appearance): Kagamine Len, Kaito, Kagamine Rin, Megurine Luka, and Meiko.  

And without further ado, I present "Alice in Musicland"!  Enjoy!
