Sol LeWitt’s wall drawings – some 1,200 sets of instructions for turning architecture into art – range from the simple (e.g. drawing lines in patterns going up, down and to the side) to the kind of full-room, immersive installation currently on view at Paula Cooper Gallery. Energizing but restrained, a matte, fresco-like orange tone dominates, setting off multi-hued, isometric pyramids of various colors that seem to float through space. In the center of the gallery, white enamel on aluminum sculptures resemble tips of icebergs adrift on the gallery’s polished concrete floor. Surrounded by angular geometries in the cavernous rectangle of the gallery, visitors inhabit a parallel universe governed by alternative rules of color and space. (On view on 21st Street in Chelsea through Oct 22nd).
