@TheHermit,
Self indulgent, northern hemispherical, hog wash. The twelve signs of the zodiac, do not seem to include much of the skies over the southern hemisphere, excluding the passage of equinox in the regions of the equator. So in all, much of what you speak of only applies to lets say two thirds of the universe at best.
A cube by the way has more facets than those which you mentioned, included are the paralell divisions both horizontally and diagonally. Giving you 16 imperial diagonals, 12 shared diagonals, 3 complete outlines, resulting in 12 new corners and 8 shared centres. None of this by the way includes inside the cube.
I don't want to be the prude but if we are going to talk of the universe in such measures, I think we should include the part you may not be able to see outside the bedroom window.
