The Carpenter Center for the Visual Arts has mounted one of Gonzalez-Torres's signature works. "Untitled (Placebo - Landscape - for Roni)" (1993) is a sumptuous carpet of hard candy spilling over the concrete floor, warming the modernist chill of the Le Corbusier building. Each candy is wrapped in gold cellophane, and visitors are invited to take a piece to eat. (Another version of "Untitled (Placebo)" opened this month at the Williams College Museum of Art in Williamstown.)
