Sweet! I bet POV would be a great program for making textures for real-time
graphics stuff.

Really nice, including the texture(s). The little bit of random placement of
each brick is a nice touch, too. Good brick walls like this always inspire me,
for some strange reason.

Thanks :)
Do you mean textures for 3d games and 3ds Max?

That's what I meant, yes. A general macro for making a texture seamless
would be cool, but I have no idea where one would start.

Isn't it extremely slow to render? How about making each brick a
similarly-generated heightfield instead? (I know that you can't achieve
the *exact* same level of detain with heightfields, but for bricks I
don't think it matters, unless you intend to look them from *really* close.)

The last time I tried doing large walls with height-fields, it was very
slow and sometimes I couldn't render because of not enough memory. But
then it was on a smaller computer than I have now. Also the bricks didn't
look as nice...
Currently I tried making simple bricks with triangles using the same
method for placing the bricks with very interesting results:
The triangles rendered slower than the isosurface bricks - about 30%
slower! This was using 3.7 beta 36. I haven't tested on version 3.62

Actually it's not slow. It's not fast either ;)

I wrote some mesh-weathering macros which can create bricks using the same
technique. Walls like this rendered with my macros render something like 10x
faster than using isosurfaces, although as you say there can be a large memory
hit if you want close-up detail. You only need to declar a small number of
different brick meshes in an array, however, then just pick, rotate and texture
them randomly when placing them.
This image contains less than 10 individual meshes for the stonework (not
including the statue):
