Three Linked Cubes – a series of rectangular bays with one side open and with side panels of alternating two-way mirror or transparent glass – has a dual identity. Placed outside, it is an opened pavilion illuminated by the sun; placed indoors, it is transformed into Interior Design for Space Showing Videos. Here, various video monitors and speakers are placed to allow three separate programs for audiences subdivided into six groups. The effects of the changing illumination from the video images reflected on the glass panels affect the mirror "ghosts" of audience members seen in other enclosed bays on the divider. The work is both a functional exhibition design and an optical artwork, displaying both the video images and the spectators’ reaction to the video-viewing process in the social space of the video exhibition situation. Dan Graham, 1997
