Can the Moon be given an earthlike atmosphere?

I have to agree about using a drawing program like
POV-Ray, one can do rather a lot with that (or Moray,
or 3D Canvas, or any of a myriad of other such
programs).

Joe, I took a look at the design you have there, and
it looks pretty good. I was thinking that if the
mirror was missing 1/3 of its reflective surface -
that is, a 120 degree wedge removed, replaced by an
equivalent counterweight - then if the station rotates
1440 times every 24 hours, the mirror could rotate
1439 or 1441 times in 24 hours. Thus, every window
would have light shining in for 16 hours, and darkness
for 8 hours, with the dark portion slowly migrating
around the torus once every 24 hours.

One might also want to extend the "spike" portion of
the hub out to the axis of rotation of the mirror,
which would rotate on magnetic bearings - that's my
first guess as to how to keep the mirror in a fixed
position relative to the station, as otherwise over
time the masses of the station and mirror would
gravitationally attract.
