A large canvas. Landscape format. Slightly curved crossed by parallel straight lines to establish points all over the work. One larger and one smaller circles are drawn on the surface; tangents from two directions from the circle edges are aimed to hit each point thus each point has fours short lines directed from it; the intervening part of the line is not shown. Within the circle areas, of course, it is possible to make only two short lines. The actual drawn edges of the circles are erased. The result is movement across the canvas. The idea was from the pattern made by water from dripping tap hitting stuck crumbs in a sink
