Messages tend to exist attached to a surface. Billboards are pasted to the sides of buildings, email messages come to us on a computer screen, and words in a book are attached to bound pages. This book is an exploration of messages that are not attached, detached messages. Think back to the movie The Wizard of Oz. Now, try to remember the scene where the Wicked Witch of the West flies through the sky and writes "SURRENDER DOROTHY" with the smoke of her broomstick. Skywriting is a perfect example of a detached message because it used the sky as a medium for communication. Currently, this type of communication exists mostly as novelty, is infrequently experienced, and thus often overlooked. Detached messages extend beyond the communication medium into space and the bodies inhabiting those spaces.
