Complex underlying structures caused the
canvases to
bulge or reach
out along the wall or into the room; a sequence
of 12, gradually changing forms was based on the pages
of a calendar from which successive pages had been torn; and finally, in work from 1972, the architectonic quality
of the paintings was discarded in his Kite Paintings, in which unstretched, painted
canvases were suspended from rods and interrupted by cords and threads hanging off and passing through them.
