Manhattan’s city grid and its amazingly functional, mystically aesthetic, and borderline occult qualities are currently being worshiped at the Museum of the City of New York with historic artifacts, hand-drawn maps and more neat stuff. Hop on over to the sister exhibit of futuristic schemes to accommodate a million more predicted New Yorkers. See some far-out fantasies like the Tabula Fluxus — a second city grid growing 700-feet above ours, Inception style — or the Projective Exceptions — the proposed cramming of various rounded structures into every street corner orifices or crevice possible. Ouch.
