In 1981, Graham started work on a decade long project in New York City. The work "Two-Way Mirror Cylinder Inside Cube and Video Salon" was part of the Rooftop Urban Park Project. Graham worked on the piece in collaboration with architects Mojdeh Baratloo and Clifton Balch. This transparent and reflective pavilion transformed the roof of 548 West 22nd Street into a rooftop park. The pavilion captures the surrounding landscape and changes of light creating an intense visual effect with the sky. The "Two-Way Mirror Cylinder Inside Cube and Video Salon" has become one of his most well-known works throughout his art career.
