A few weeks ago, I heard about this innovation in communication called Grafedia, where email addresses are sprayed as grafetti, then cell phone or computer users who use the email address get a special return message, but I couldn’t imagine its use. Well, apparently, plenty of other people could!

Sending a message to "in_here(at)grafedia.net" — spotted in Brooklyn — returns a digital image of a man sitting beside a stream. Another New York grafedia artist underlined the word "McDonald’s" in blue on a billboard for the fast-food chain; a message yields a portion of a kitschy sign instructing viewers how to avoid choking. Some people use grafedia as a promotional tool, linking to images or text that includes a personal Web site address or a rock band’s name. An art teacher in Australia creates treasure hunts, with one grafedia image pointing to the next.
