The Letterman Digital Arts Center (LDAC) is the new home for Industrial Light & Magic, LucasArts, and Lucasfilm Ltd. Once a military hospital in the Presidio of San Francisco adjacent to the Palace of Fine Arts, it has been redesigned to fit the needs of the entertainment mecca. Before a single screw was turned, George Lucas personally oversaw the entire process of digitally conceptualizing and rendering the rooms in the buildings.
