Yeah, it's difficult to make the summer seem brighter, since the winter is
mostly white and light grey, so I settled for making it a lot more colorful.

The wall is from code that I designed called the ISW (Iso-stone Wall). 
Originally, it started out as a port of the mur.inc to iso-surfaces, but I
found that mur.inc wasn't adequate for what I wanted to do.  So I rewrote it
from the ground up.  I built a lot more logic into the laying of stones, and
included a bunch of macros to allow me to make things like towers and tubes,
each with variable radius.  These are done by permutation functions to the
isosurface function.  I want to add a spherical and disc like as well, but
that's not done yet.  The arch is just a very short (one block long) half tube.

Incidentally, it's not just for stone.  I've made some really nice hardwood
floors with it and the isowood.inc just by re-defining a bunch of macros.

At some point, I need to write up a quick doc for it and then I'll release
it.  The code is pretty clean, but it's tricky to see what needs doing to
get the right effect without some guidance.
