This is a book of stereogram pictures. You will have to look at them at a certain angle or distance and relax your eyes to see them. It also might help to double tap the picture quick two times so you can make it a little bigger. Flipping the picture vertical or horizontal, could help with some of them. Everyone is different in the way they focus their eyes on stereograms, so it may take some experimenting. The main thing is to have a little fun with them. Oh, they are color, so I am not really sure if they will work on the black and white kindle.
