Japanese art director and copywriter, Masashi Kawamura, has created the Rainbow In Your Hand book, which is 36 pages of black paper with a small strip of the color spectrum on each page. As you flip through the book with your fingers (as seen in the photos), it generates the illusion of a rainbow. It kind of reminds me of those pencil drawing animations we drew in the corner of our notebooks back in grade school.

You can buy the book at Heeza for 11.50 Euros ($18 USD).
