is there a way to make a simple spine, such as a win glass, with a inside
surface and an exterior  surface? I suppose that would be a "closed" spine
rotated around the z axis. I think I am going about it the wrong way in
moray.

where "x:" is a connector

It makes no sense using variable-width font when readind and specially
when writing news articles.

  By writing formatted text (or ascii graphics like in your case) with
a variable-width font you are assuming that everyone else in the world
is using the exact same font as you are. Naturally this is not so but in
just a few cases.
  Since no-one else will probably have the same font configured in their
newsreader as you, they will see the ascii art completely screwed up.

  When writing formatted text (or ascii art) you should always use
a fixed-width font the ensure that other people (who also should be
using a fixed-width font) will see what you are seeing.
  And naturally you should use a fixed-width font when reading news
articles to ensure that you see what others wanted you to see.

  Using a fixed-width font is the only way to be sure that characters
will align vertically the way you (or anyone else) intended.

was there a problem reading my post?

The ASCII art, at the bottom, was just a simple illustration to help convey
a point. . by the way looks intelligible in fixed with or variable width; it
is not as though I was making a picture of Santa  :)

  Honestly I'm not sure what kind of picture you were trying to make
since the amount of spaces you used is screwed up:

  Simply use fixed-width font next time and there shouldn't be any problem.

It makes perfect sense to *me*; he obviously wants a wineglass-
shaped rotsweep.  So the spacing isn't perfect...my optical
pattern recognition ability is sufficiently advanced that I can
still make out what he's getting at. :P
