Medusa's head in profile, her hair a tangle of black snakes with long pale serpents looping around her face and shoulders. Square frames with spiral centers sit among the coiling serpent bodies and stand in for the finder squares. Dense black snake curls and the inked shadow around the neck form the dark modules, while white skin and scaled coils give the light ones. Sharp black on white contrast and fine hatching on the serpents keep the pattern legible.
