Swarming Striations at time 130Method '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. By run 130, the points have formed a swarm near the center.
