Motion Silhouette is a Japanese interactive children’s book by Megumi Kajiwara and Tathuhiko Nijima. It features pop-up silhouettes in-between pages. As a light source is directed toward either side of the pop-up silhouette, a moving image is projected onto the page to help tell the story. The book is made to order by hand (for about $60). It is not available via Amazon but only through their website.
