Handicrafts - Paper craft

I've been cutting and sticking paper with my kids for a while now, enjoying their creativity as they make collages and other creations. But that is nothing compared to this castle, recorded by Tokyo Bling:

According to the blog, this papercraft creation took four years for Wataru Itou to make, and includes a working train and lights. You have to go and see the pictures over at Tokyo Bling. They are incredible. The whole structure is made from painstakingly cut and folded paper (apart from the mechanical bits).
