Hi again,

The Z_Align macro is not only good for sky_spheres, it's good for many things.
Depending on what you want to do it can be a better alternative to
Point_At_Trans, since it gives you more control over the final orientation.

The Lerp macro is for linear interpolation. It just makes it easier to choose an
arbitrary value between A and B. I could have made the scene without it, but
decided to use it since it simplifies the code a bit. (But looking at it now, I
should have declared a variable to reduce computation times and to keep the code
cleaner, haha.)
