A Cookbook of Invisible Writing, written and designed by Amy Wu, is an introduction to analog steganography, a type of secret writing that is hidden in plain sight. It is an invisible ink coloring book, recipe book, puzzle book and artistic research book. This book also serves as a starter pack to run workshops for those who are interested in alternative forms of communication. A Cookbook of Invisible Writing provides a wide variety of invisible ink recipes and other communication techniques that may be used to subvert surveillance, bypass censorship and make visible the struggles of minorities and other marginalized cultures. Additionally, it aims to inspire communities to develop their own new poetic and playful forms of communication as a way of nurturing social bonds.
