This video is entirely done with computer generated imaging. While many of the locations exist in real life, they were recreated for the film. The creator is one talented artist who's dedication to his work is easy enough to see in his work. I have shown this video to many a classmates, but this is definitely worth watching again.
The "star" of the film is the Phillips Exeter Academy Library, which is the largest secondary school library in the world.
