10. Grand Central: Arches, Towers, Pyramids

Jackie Ferrara-Grand Central Arches, Towers, Pyramids in Grand Central subway station

In 2000, artist Jackie Ferrara created Grand Central: Arches, Towers, Pyramids, a series of ceramic mosaics on a number of passageways and waiting areas in Grand Central.

The mosaic’s simplicity, repetitiveness, and mathematical nature make it seems like “images on a strip of film, or a line of faces framed in the windows of a passing train,” according to Ferrara. As passengers walk along the platforms, the images shift to reveal an almost meditative atmosphere, with no two images being the same.
