MirrorMask

Ok, I'm cheating here. This is actually a movie, but since the main script writers are Dave McKean and Neil Gaiman (who is just super cool) I'm including it here.

The star of this film is the computer effects. They are utterly spectacular and artistic. The story comes a close second; it is simple and enjoyable.

MirrorMask is also a book (that I haven't read,) which was published after the movie came out and showcases much of the art from the movie.
