Moynihan Train Hall, Penn Station, New York City. Across one wall of the new train hall that recently opened in the historic James Farley post office, there is a display of constantly changing photos from the old Penn Station. The photos are b&w, then slowly change to a color tint. Pink circles appear over the photos to be printed. As the display changes and a new row of photos appear, one sees the sprockets from the film. It's very cool.
