Turrell has re-sculpted the massive interior of the iconic rotunda with tiers of white fabric over unseen scaffolding. Unsagging and seamless, the perfection of the material allows the physicality of the light to become the primary focus as both natural and LED lights shift from one color to the next at the speed of a sunset. This piece, titled Aten Reign, is completely immersive, altering not just the 6-story ceiling, but changing your entire perception of the world around you (at moments I forgot what “white” looked like).
