Pretty awesome!
Argh, it's so hard to figure out what I want to rate this.
The first time I watched it, I thought it was super impressive; I just didn't get the point. I then read your comments, and after watching it a second time, it made sense. I then watched it a third and fourth time to see what I missed :P So, no, the message wasn't clear on the first run through.
I don't usually watch things more than once or twice in a row, but you have a knack for keeping me interested; even with the Professor Layton series (Which my friends and I quote daily.)
Art and backgrounds were great! The animation fit the song well, and the cuts were perfectly timed. Also liked the fast forward effect you used in the classroom scene.
Okay, I've decided to 10 this.
