A Cookbook of Invisible Writing, by Dutch artist, designer and teacher Amy Wu, is an introduction to analog steganography—a type of secret writing that is hidden in plain sight. This book serves as a starter pack to run workshops with groups who are interested in alternative forms of communication. It contains invisible ink recipes and other invisible communication techniques that may be used to subvert surveillance and bypass censorship, but also inspire your community to develop poetic and playful forms of communication to nurture social bonds.
