Since the mid-1960s, conceptual artist Dan Graham has been investigating how spaces affect human behavior, how art and audiences are connected, and how works of art are linked to their physical, social, and economic contexts. His works have included color photographs of suburban tract homes; interactive performances, films, and video installations; and glass and mirror pavilions, which he has been making for more than twenty years. For the Minneapolis Sculpture Garden he has created a large geometric maze with walls that provide both transparent and reflective surfaces. As we interact with the sculpture we both see and are seen, view the surrounding environment and our own reflections. The piece conjures up questions about inside and outside, about public and private spaces, and—as the reflective surfaces respond to the motion of clouds and sun—about nature and culture.
