Wow...it took me so long to do this that I almost fell off page 1!
  The above tank doors/walls are completed.  I'm not completely happy with the result, though.  I'm willing to bet that I tear that top section out in a few years and try something else.
  I was trying to create an "in wall" look, while still having something that I could open.  I think I succeeded, but they just look so plain compared to the stone work below.  Oh well.
