A long time ago, you needed a talented team and one helluva lot of cash to make a CGI movie. The talent, you still need that. The cash, though, not so much. I'm thinking that nifty little fantasy adventure short was helped along greatly by the music, but you'd expect a hi-fi nerd like me to say that. Recommended.
I always figured that, once the "oooo shiny" factor wore off, the cost of making CGI would drop like a rock. Like everything else that's digitized, it's really just one really big number, and numbers are simple to copy and very difficult to get people to pay any significant amount of money for, no matter how much time, talent, and effort it took to find just the right number to make an awesome multimedia experience.
