If you suddenly decided to see a rainbow it would be really problematic – not only you’d have to wait for the rain to come, but there should also be a sun shining through the falling raindrops.

Luckily, now there is this cool rainbow creating book! It’s a flip-book, but rather than seeing animation, it creates a 3D rainbow in your hand.

“Rainbow In Your Hand” started as a personal project in summer 2007, and was soon published from a Japanese bookstore “Utrecht”. Since being published it has been featured on Japanese TV, Newspapers, major news & blogsites like yahoo news, coolhunting, fffffound and now on boredpanda. This book aslo won this years NY ADC silver cube. (via 1 2)

Just be sure not to flip it too much, as others might think you are sending some kind of secret rainbow signals to them.
