Motion silhouette: a book with animated shadows

You already know about pop-out books, but Motion Silhouette is a new kind of book. Created by Japanese designers Megumi Kajiwara and Tatsuhiko Niijima, it has pop-out paper cutouts that come to life when you play with a torch’s light. The shadows interact with the printed content in a very cool manner.

On this post, you can see a few images from the book, as well as some animated gifs to illustrate the concept, but you should really check out the videos on the project’s Tumblr.

The books are made on-demand, so you have to email the authors from their website to place an order. Each book costs 6000 yen (around $60).
