Jim Campbell's interactive work, Ruins of Light, consists of four stainless steel columns containing five 32" video monitors each, located in the central food court at America West Arena. Campbell, an engineer as well as an artist, developed the computer software that operates the artwork. The artwork is programmed to unique sequences of imagery every day of the year. Each column also houses a discreet video camera that literally “captures" the viewer., making them an integral part of the experience of the artwork. Images of the viewer are superimposed with the images on the monitors which include among others sports, saguaro cactus, and historic sculptures. Selected images of the viewer are “frozen" in time on the monitors, allowing the viewer to see himself or herself simultaneously at varying points in the immediate past.
