But it's impossible to move beyond the sky_sphere because it's infinite. It's
merely rendered as a sor of "backdrop" to the scene, the same regardless of
camera position. Kind of like those skies in Doom and Quake that don't appear
to get closer as you move.

Of course, that doesn't mean there's nothing else there... Suppose we live in
a three-dimensional universe that's like a "slice" of a four-dimensional one.
There's a whole nother dimension that we can't possibly get to.
