100% ActionScript? Damn, I'd love to know how to make things like this. All the 3D stuff is impressive, to say the least. In particular, the transformations on the letters are really nice-looking, and I especially like the spinning cluster of balls that appears at the end.
Obviously, the presentation is a bit rough around the edges, but I'm sure you could easily smooth things out if you wanted to. All in all, this is a neat little demonstration.
Plus, the music makes me smile. :)
I gave you a three for effort. Good job on the 3D system, but the music and the content that came after about 1 minute of the movie sort of killed the potential it had.
