Today's coolest book picture

From the Boston Globe's "Big Picture" photo blog (link):

Images of books on shelves are seen projected on the walls of the Tower of David in Jerusalem's Old City - part of a show called "Night Spectacular" on October 7, 2008. The Tower of David is a massive citadel that, over the centuries, has served as a fortress, military barracks and cannon position. These days, the Tower serves as a popular tourist site.
