Stippling Pattern 1 (Force Repulsion)

This pattern is actually a random pattern 3, but I have modified by using the principle of magnet repulsion and attraction.

However, the calculation for the hole placement will be determined by the intensity of particular area in the image. The pattern result produced by this pattern is not only depend on the parameter that has been chosen, but also depend on the image itself. The recommendation image that I suggest is the one that has a strong colour separation between the area such as silhouette image.
