Can u do a version of the starwars coruscant, but with a "real" Galactic Imperial Grandeur to it, instead of the slum-like, tired looking and dull veneers. I suggest a combo of different surfaces, natural, abstract, bryce... Japanese concept of symmetry might work, I don't know.
HA! I love "hmmm, what if moments" they turn out to be the best art. I love the tenticals milking the brain matter. It reminds me of some sort of parasite from War of the Worlds by H.G. Wells. Just awesome!
