Inspired by 'Eon' a novel by Greg Bear. Actually mr. Bear gave permission for 'Eon' to be used as topic for the XX CG Society Challenge (the very first in which I entered). Here we see two of the main characters looking at the landscape of the fourth chamber. In the book an asteroid is discovered, inside there are a series of chambers (or habitats) were gravity is mantained by the asteroid's rotation on its horizontal axis, so thar all lanscape elements are spread on the wholòe inner surface of the chamber. I tried to transmit the feeling of vertigo I had when I first read the description.
