There's a story behind this story; parts of it are actually real! Last year I got an email from a fellow who ran an iPhone app business and was hosting an art show there, and asked me to write about it and visit it if I was in New York. There were links to pictures of the exhibit, which I followed.
The story jumped into my head as I was looking at the pictures. So the email in the story is real, even though my name's not Stan and I don't work for a newspaper or am in New York. The exhibit itself was real when I wrote the story, although it's probably long been taken down. The address is real, the artist's name is real.
Of course, little if anything else is.
I shopped it around to maybe a dozen magazines, and Tor has had it since December. It will be in the book I'm releasing next year, Voyage to Earth and Other Stories.
