  I think that you will find that the people in this thread know all about
how the sky sphere is implemented. The sky sphere is not even really infinite.
It exsists everywhere something else isn't. More specificaly everywhere there
is no object the skysphere fills in the unused pixels. A fancy fog of sorts.
