Daoloth

[Daoloth was not] shapeless, but so complex that the eye could recognize no describable shape. There were hemispheres and shining metal, coupled by long plastic rods. The rods were of a flat gray color, so that he could not make out which were nearer; they merged into a flat mass from which protruded individual cylinders. As he looked at it, he had a curious feeling that eyes gleamed from between these rods; but wherever he glanced at the construction, he saw only the spaces between them.
—Ramsey Campbell, "The Render of the Veils"

It is inspired by vision of Render of the Veils himself.
