The Hall of Presidents: There was shattered glass all over from the exhibit cases. The darkened hall was lit by using a long exposure and shining a flashlight to outline the unique ceiling. From the guidebook:

A separate new exhibit area is filled with the memorabilia of eminent U.S. chief executives: Washington, John Adams, Jeffereson, Jackson, Polk, Lincoln, Cleveland, Wilson, the Roosevelts, Truman, Eisenhower and Kennedy.
