UnBeige, mediabistro.com's design industry blog, had an item yesterday about the cover of the new issue of Opium, which contains a nine-word short story by artist Jonothan Keats called "Time." The only thing is, as UnBeige learned from Wired, the cover employs "a double layer of standard black ink, with an incrementally screened overlay masking the nine words." In other words, it looks black now, but after prolonged exposure to ultraviolet light, the top layer will fade and reveal the words underneath, one at a time—and it will purportedly take 1,000 years for the process to be complete.

In the meantime, you could always try to track down all the words to Shelley Jackson's "Skin."
