When light passes through the fenced walls of the installation, movement and patterns are created and thus can either become an area of calm and relaxation or can cause a slight feeling of claustrophobia.[3]The art installation, made in 1983 by Robert Irwin, was originally placed on the rooftop plaza of the City of Seattle's Public Safety Building.[5] The University of Washington Facilities Services devoted most of the summer of 2006 to preparing the ground for the reconstruction of the art installation.When the University of Washington had shown interest in having the installation be recreated on campus, Irwin helped select the site but he then substantially adjusted the design.The original installment utilized red flowering plum trees but Irwin replaced them with Winter King Hawthornes in the adapted version.
