The "Metal Elephants of Arcturus" is the name given to a series of alien monoliths of unknown origin found on the surface of the medium gas giant Arcturus 1 in the year 2350.

So far 156 monoliths have been found. They all resemble abstract elephant heads, with one eye located on both sides of a half-circular body. The height of the structures vary between 10 to 100 metres, and the construction material is unlike any other known elelment: strange, blue colored metal-like material, which appears to be indestructible, and which seems to be magnetically linked to the core of the gas giant itself...all attempts to move the monoliths have failed due to this magnetism; in all cases where excavation teams have attempted to move them they suddenly seemed to weigh a million tons and so all such attempts were abandoned a long time ago.

Some observers have suggested that the objects themselves are in fact an extraterrestial species, believing this to be the first example of an "artefact life form"; intelligent creatures made from living metal. But current scientific evidence doesn't support such theory; all attempts to communicate with the artefacts have failed, and tests made to them have not indicated the presence of intelligent life. Nowadays it is widely accepted that they are most likely remnants of some alien civilization, possibly objects of artistic or religious meaning. Although some have suggested that the objects could also be a practical joke left behind by an highly advanced alien species who left our dimension a long time ago.

Made this pic to practice fog, sky and dithering, while keeping the color amount at 16.
Went for that "Purple Saturn Dayish" look and feel, and indeed, I think the end result is full of "it". :D
