It is a mile-high structure of moving two- and three-dimensional images, interlocked in space and time. It's got everything in it. Leni Riefenstahl films. The sculptures of Michelangelo and the fictional inventions of Da Vinci made real. World War II dogfights zooming in and out of the middle, veering out over the crowd, shooting and burning and exploding. Scenes from a thousand classic films, flowing and merging together into a single vast complicated story.
