Papercraft....more like mastercraft! What?

I really dropped the ball with the title of this post but I've come too far.

Awhile back I posted about papercraft and what little bit I've fooled around with it. Then today I see this thing.

Now I realize that I'll never have to post about papercraft again because this guy nailed it. It was made by Japanese art student Wataru Itou and took over 4 years to create. It features lights and a moving train. A fucking moving train made out of paper.
