That looks like a wall, but it’s not.
Robert Irwin designed this piece specifically for our @hirshhorn, squaring off the building’s ? shape. A large sheet of scrim (cloth that looks opaque unless there’s light behind it) creates the illusion.
More works in "Robert Irwin: All the Rules Will Change" challenge the visitor’s perceptions about light and space. See it through Sept. 5. "Square the Circle" 2016. #RobertIrwinHH
