"6 x 6 x 6 x 2 is a painting in multiple parts on two facing walls. The origin of the work was my visualizing two panels separated by a space; the edges of the panels to either side of the space were jagged, like saw teeth or as if notched. The irregular edges make us see the shape of the space between them, a space that in relation to the panels is negative but just as much a part of what we see as the two panels whose edges produce it."
