Leathery alien passages shaped like orifices and reproductive organs. Haunting, sexual nightmares, where the gothic merges with biology, where pleasure meets pain. Eyeless insectoid creatures with human characteristics. I recall the late "Alien" writer Dan O' Bannon saying that Giger used to consume opium to quell the visions that disturbed his slumber. And, now the glorious genius, this prince of darkness, is gone. But his biomechanical images will remain, to haunt our dreams.
