Swarming Striations at time 90Method 'K' uses an underlying set of points as the structure of each drawing. In series 002, the point positions are subject to swarming behavior. Sweeping laterally across the field groups the points according to their x position. Each group is then sorted according to their y position and a single line is drawn through the sorted points in each group. Every 1 in 50 lines is omitted. The points are initially organized on a grid; by run 90, the grid is a distant memory and points are so unevenly spaced that ridges and cliffs and other breaks in the apparent continuity of the striates surface register.
