In Chicago, Leonardo the Inventor and Decoder

Thanks to Ron Jones for this (from the New York Times):

There are no albinos with red eyes and bleeding thighs stalking the galleries of the Museum of Science and Industry here. There are also no dead curators sprawled naked on the floor with pentagrams drawn on their chests in blood and scrambled Fibonacci series scrawled at their sides. But there is a "cryptex" on display: perhaps the only one ever constructed. It is a prop from the leaden movie of Dan Brown's best-selling roller-coaster ride "The Da Vinci Code": spell the right word on its dials (if you could only get at them), and the Holy Grail is yours.
