Reader Jeff Mitchell brought his artwork to my attention. He calls his illustrations "Digikyoe":
Digikyoe is an adaptation of "Ukyoe, meaning "floating world," which refers to the impetuous young culture that bloomed in the urban centers of Edo (modern-day Tokyo), Osaka, and Kyoto. It is also an ironic allusion to the homophonic term for "Sorrowful World," the earthly plane of death and rebirth from which Buddhists sought release."
Go visit his site to see more striking, creepy images. I particularly like the animated ones, which I have excerpted below.
