We speak with paper engineer Robert Sabuda, who creates splendid pop-up books; his most recent work is a pop-up version of C.S. Lewis' "The Chronicles of Narnia." We also talk with the author of "Merry Xmas, America" which features photographs of some of the most spectacular and even outrageous Christmas light displays from around the country. The book seeks to answer the question of what drives certain people to devote such time, energy and money to creating such lavish holiday home displays.
