Are there hidden corners in your computer files?
Does that shopping list hide a secret message?
Is that a typographical error or a hidden signal?
Can you slip an invisible message into a picture of a kitten?
The answers to all of these questions and more are described in this ground-breaking interactive book. Learn how even the most precise computer files can disguise hidden messages where they can't be seen or found. Then hide your own message with illustrations that actually work. Each of the five major chapters include an introduction, several sections of explanation and a working illustration so you can actually hide your secrets as you read and learn.
Best selling author Peter Wayner developed this book with working diagrams so everyone can explore the hidden corners of the bits and bytes of your computer. Most of the descriptions in the book are kept to a seventh-grade level so the widest possible audience can enjoy the fun of learning just how many hidden layers there can be to simple information. The text is deliberately kept short and focused to appeal to the widest possible audience. The result is a concise journey through the philosophical looking glass where nothing says exactly what it seems to mean.
