Kryptos sleuths may finally get some help cracking the CIA sculpture that has confounded amateur and professional cryptographers for two decades. Artist Jim Sanborn, who created the cypher sculpture in 1990 for CIA headquarters in Langley, Virginia, plans to release a new clue to help puzzle detectives solve the last 97 characters of his masterpiece. The new clue is to be revealed in a New York Times article this weekend, to mark the 20th anniversary of the sculpture, which was dedicated Nov. 3, 1990. It will be the first clue Sanborn has revealed in four years, after he corrected a typo in his sculpture in 2006 to keep crypto detectives from being derailed in their search for solutions.Kryptos Artist to Reveal Rare Clue to Baffling CIA Sculpture | Threat Level | Wired.com
I’m a fan of Sanborn’s work. When I worked at the University of Houston, we commissioned him to create this stunning piece (plus two others) for the main library, which housed my two offices. Sanborn’s sculpture gave me reason to pause outside the building every day.
