Critic/theorist Rosalind Krauss famously explained modernism as the divorce of architecture and art. Here, though, an artwork feels happily married to a space from the twilight years of high modernism. The mosaic (which I've always loved, but just recently found out is titled 'Geometro') seems to update the understanding of classical spaces as proto-cinematic experiences; before the proliferation of print/mass media, art was a "place" people visited to see a story told in stained glass, fresco, mosaic, or sculpture. Alexander's "storyboards," however, are abstract—describing an unspecified tension as opposed to a narrative. The kinetic energy of the metro—arguably the most utopian token of the machine age—animates the panels like sunlight "powered" the screens of medieval cathedral windows. The artwork is meant to be experienced in motion, and no still photograph can do it justice.
