These drawings are created from a sheep trail simulator. The light and dark areas in an image represented the abundance of grass, and the area was populated with virtual sheep that ate grass and followed trails where other sheep had been. To make colour, some sheep preferred red grass, others blue and the remaining preferred green grass.
