    The sky_sphere isn't really at infinity though. It's not even
a sphere. It just appears that way.

    In fact it's really everywhere in the scene something else isn't.
Sounds confusing but it's not. The method of implementing the
sky_sphere is similar to the projection of the camera. Rays of light
are projected into the scene from all directions, and anywhere they
do  not  hit an object, that pixel is then turned on using the pigments
color index for that location.

    That's why no finish, normal. or texturing options are allowed.
You can't have it reacting with reflected rays coming off the surfaces
of the objects in the scene or you would end up with all kinds of
visible unwanted effects. You could, in a manner of speaking,
think of it as a massive, located everywhere,  area light.
