RAINBOW IN YOUR HAND "3D Book"

i think this is cool, holding the rainbow in your hand ;)

"This book started as a personal project in summer 2007, and was soon published from a Japanese bookstore "Utrecht". It's a flipbook, but rather than seeing animation, it creates a 3D rainbow in your hand. Since being published it has been featured on Japanese TV, Newspapers, major news & blogsites like yahoo news, coolhunting and fffffound. This book won this years NY ADC silver cube."
