No biggie.  It's always nice having a macro that a person writes himself,
and therefore understands the code perfectly, should it ever need to be
tweaked.  hehe.

Feel free to use, borrow, modify, improve, etc.

Right.  I'm not trying to write the brick-wall macro to end all brick wall
macros, but the idea has crossed my mind.  Right now, I just wanted
something that looks good from a small distance, and I've probably already
exceeded what I really need it for.  But then again, if I end up making
something that I want to put on a poster, I'll probably re-render at some
ultra-huge size.

Thanks!  I'm very grateful to everyone else who has donated their code and
macros and libraries, so whenver I come up with something that I haven't
seen before (or a new spin on something old), I try to post it here.  My
knowledge level will probably never be close to that of many others around
here - I'm barely scratching the surface of iso-surfaces (no pun intended) -
but for anyone new, or somewhere around my level, I hope to give them
something to work with.

And for anyone reading that might be afraid of trying iso-surfaces, don't
let iso-surfaces scare you.  Use Christoph's isoCSG library.  It's really
not as complex as it might seem.  Just don't forget about max_gradient.  ;-)

Indeed. The width of the mortar, the surface texture, the shape etc. is
highly dependent on the geographical area, building period, purpose of the
building, visibility of the finished wall, funds available for building, and
so on.

If it looks like the example, it'ok.

Was this macro ever uploaded? Using Google I can only find this thread. Thanks.

Probably not; I would have it in my collection. ;-)
