Could just as easily be "Weather Artists", lol. About 10-15 yrs. ago I read an unusual Sci-fi short story about a small group of artists that created "weather events". Large unpopulated areas were the stage for whatever the artist decided to conjure up. The event was televised and voted on. It was considered the ultimate artform. Yeah, strange, but interesting. Sure wish I could remember the name of the author. It may have been a short story in Omni magazine. Dang, this is gonna drive me nuts now. :)
