Now this is a pretty cool book of illustrations that are animated by using a special piece of marked plastic. The images move when the plastic is passed over them as if they were animated.
No batteries or anything are required for the images to operate. It would be cool if the images could be in color, but they are all in black and white.
Check out the video below to see the images in action, it is pretty impressive and kids especially would love this book. You can get your own at Amazon.
