The animation is about a monster whom is portrayed as a Hollywood actor who has grown old too and is now rusty. His fame and long line of movies are put to rest as his capabilities are not up to date and it is time for a more talented actor, the powerful ever-growing CG (computer graphics). The animation is not only powerful in meaning, it is artistically beautiful and very funny.
The animation does deliver a very strong message yet it is best interpreted as a big metaphor to Hollywood, especially the ending which I won’t be spoiling for you. See it for yourself and if your interested you can follow his work on his blog.
