I see what you're saying.  I based these on pics I had from my trip to
France, though.  Obviously these things varied.  However, it's really easy
to change this sort of parameter (my stone laying algorithm is really nice
that way) so I'll see what I can do.  It might knock the supports off,
though.  Right now there's a 121 correspondence between supports and
crennels (the second tower angle is off), and I like that symmetry.  Have to
see what I can do to change it.

No problem.  Most media isn't too bad, but this is the first time I've
worked with scattering,  Upping the extinction and splitting the light in
two (one that reacts with media and one that doesn't) seems to be having
some effect, but it's not perfect yet.  Alas, it's also slowed down my image
badly.  It'd been going for 13 hours when I got up this morning and was only
half done, and all the important changes were in the bottom of the pic! 
Arg.
