One of the most enjoyable ways to acquire a headache
Published by Thriftbooks.com User , 16 years ago
This book is one of the most pleasurable ways to generate a headache I have ever encountered. It consists of nearly 200 pages of stereograms, images that are 2D but if you look at them the right way a "separate" 3D image will appear. When I first encountered this type of image, no matter how long I looked at them, I could not see the 3D aspects. However, once I saw the symbolic light, it is now very easy to do. I spent a long time looking through this book, so fascinated by the images appearing I started to suffer from eyestrain that led to a headache. It was worth it though; the appearance of the stereogram images never ceases to amaze me.
