Celestial motifs and cosmological geometries strewn across a prismatic landscape comprise “Abstract Futures” (2025), the newest public artwork to grace the walls of the New York City subway system. Designed by the feminist art collective Hilma’s Ghost, the 600-square-foot glass mosaic mural now greets transit riders between the turnstiles and escalators at the 42nd Street entrance to the 7 train in Manhattan’s Grand Central Station after being installed earlier this month.
