A recursive split fills the square with panels, each hatched, arced, tick-marked or nested, and each given a ground one or two steps apart inside Flexoki's darkest greys, blues, purples and reds. Panels the split left empty carry a ruled register and one corner worked hard. One oblique wedge is cut through that order and repainted in paper, yellow and orange, with no middle step between. A few panels inside stay dark, a few outside break light.
