Entropy-reversing machine

The entropy-reversing machine is a fictional device featured in the Cthulhu Mythos novel The Horror from the Hills, by Frank Belknap Long.
== Description==
The entropy-reversing machine was invented by Roger Little, who also refers to it as "the time-space machine", as the reversion of entropy produces an effect akin to temporal reversion. In the case of man-made objects and living beings, the result is always destructive. While the effect varies across different materials, it has been estimated that ten or fifteen minutes of exposure are equivalent to reversing a billion years of entropy.
Physically, the machine consists of a complex mechanism of metallic globes of multiple sizes, as well as portions of globes and crescents, all intricately linked. It is a large device, but light enough to be carried by two men with ease, and can be mounted on a car for transportation. Once it is set in motion, the globes and crescents start to move with variable speed, synchronizing and desynchronizing until the entire set merges into a form that Little identifies as a fourth-dimensional figure. This is described as "a shape paradoxical, outrageous, unthinkable—a sphenoid with a non-Euclidean face, a geometric blasphemy that was at once isosceles and equilateral, convex and concave".
After the figure is formed, the machine emits a blinding greenish beam that reverses entropy. Even the briefest exposure to it causes organized matter to dissipate. Walls and other man-made structures crumble to dust. Life forms caught by the ray are annihilated, although incredibly ancient forms of life such as Chaugnar Faugn can withstand several minutes of continuous exposure before their physical form starts to collapse. While this isn't enough to actually kill Chaugnar Faugn, it is enough to banish it back to the higher dimensions it originated from. (: The Horror from the Hills)
