Everyone here needs to watch this video, The Third & The Seventh. It's 100% CG, and everything is all done by one guy. All the animation, 3d, and music is all done by just this one incredibly talented guy. If you have the option, watch it in HD and fullscreen it. If you have a really kick ass pair of headphones or something watch the movie with those in, I feel that the musical score is really important to what makes it so beautiful.
I feel like this is one of the most beautiful and most incredible animation I've ever seen.
and I feel no shame about getting all emotional while watching, I felt it was that incredible.
