This is a four year stop-motion project by Takahide Hori, it is simply amazing to think anyone can create anything like this alone.
I have no idea where to start so read this article to find out more.
What I can tell you is I loved it. There are some crazy creations in here, there are also some parts that will have you chuckling away contently. But all laughing aside the story line is surprisingly gripping, and I think you will be glued to see what happens next.
