If you ever saw the movie version of Anne Rice's novel Queen of the Damned, you'll remember the final scene. As two of the vampire characters walked off, the human world around them began to speed up. I always thought that was a particularly neat visual metaphor for immortality.
Somehow the maker of this gorgeous video did the same thing with the city Paris. According to Vimeo it was made entirely out of photographs.
