Shelley Jackson's Ineradicable Stain: a "mortal work of art"? A short fiction published exclusively in the form of tattoos on the skin of volunteers, one word at a time.

Each
participant in "Skin" must agree to have one word of the story
tattooed upon his or her body. The text will be published nowhere else. Participants must accept the word they are given. Participants will be known as "words". The
author will make every effort to attend the funerals of her words.
