I'm just putting the finishing touches to a macro to generate block walls 
and stone walls.
Here's a little taste of what it does:

Ooooooo...   Very nice!

I had a brick wall macro, but I was never entirely happy with the results. 
Mostly, what I didn't like was the fact that POV-Ray doesn't allow you to 
overlay textures.  e.g. giving each brick a texture, then overlaying a 
semi-transparent texture on the entire wall.  Perhaps there are ways around 
that limitation, but I couldn't think of anything that worked well.

I especially like the "slate" wall.  This is very impressive.

You can overlay textures so long as the upper layers do have some 
transparency. I have seen a technique that produced reasonable results using 
the brick pattern (though I've never used it). There's a tutorial at 
http://www.shipbrook.com/jeff/raytrace/bricks.html covering something 
similar. I don't know if that technique is worth exploring.

Very pretty. Spline-based?

The top one is.
The bottom one uses an array of corner points.
It's actually a set of macros that use interchangeable block styles.
I tried to think of all the different ways to define a wall and did a macro
for each.

Here's one where you specify the extents of a box and it puts a perimeter
wall inside it. The holes are just CSG.

Oh! Ah! This is very nice!
I was cleaning up my collection of macros and came across a similar one by 
Dave Blandston, some years ago. That was not as good as yours definitely. 
Makes me think of your stonecol macro though.

Here's an attempt to show the block-based walling in a better light:

Ah yes! Stonecol is very old and used height fields, whereas this new macro 
actually defines the individual blocks. It does though perhaps betray the 
obsession that I've had with getting credible looking masonry over the years 
:-)

It's done.
It's available on the Object Collection at http://lib.povray.org called 
StoneWall.
