We shall see these things, and other things which no breathing creature has yet seen. We shall overleap time, space, and dimensions, and without bodily motion peer to the bottom of creation.” [said Tillinghast] … We entered the laboratory in the attic, and I observed that detestable electrical machine, glowing with a sickly, sinister violet luminosity.” (H.P. Lovecraft, “From Beyond”)

Definitely one for the Art Room at NecronomiCon 2015.
