James Sanborn built the sculpture in 1990 and inscribed four sections of code -- most of which looks, to the uninitiated, like random letters. While it generated a fair amount of intrigue from the start, it wasn't until Dan Brown included references to the sculpture on the book jacket of his "Da Vinci Code" that Kryptos took on a whole new life. The sudden spike in interest took Sanborn by surprise.
"I'll be ecstatic when it is solved," says Dunin, who created "Elonka's Kryptos Page," probably the most popular Kryptos website. "There's an enormous rush that comes with cracking a code." She also heads up a Kryptos-cracking team of about 850 active members.
Interest probably won't wane anytime soon. The film adaptation of Brown's book should only stoke more interest in all things Da Vinci. And there's also talk that Brown will give the Kryptos sculpture an even more prominent role in his next novel, "The Solomon Key." That's good news for Kryptos buffs -- the more minds working on it, the sooner they expect to break it.
