This book contains 25 stereograms. A classic stereogram is a three-dimensional image hidden within a two-dimensional pattern. This three-dimensional image is viewable without any special equipment. When your eyes adjust to see the image, you feel as if you're looking into a special world that's all your own. It's just so much fun trying to figure out what the images are. In the beginning you may have a hard time finding the images but you’ll see them eventually. Creating a stereogram is a combination of advanced technology and artistic ability. 25 such stereograms and their hidden images are given in the book.
