Here is my wall so far. I like the fact that the bricks are irregular. 
However, the edges of each brick is still too sharp. If I could soften 
the edges and corners, that would be great.

Well, if you want them more irregular, your f_wrinkles value needs to get
multiplied - 1.2 - 2 looks good.

Or you could use a round_box object for the bricks and subtract a single
translated wavy isosurface from its face and edges.
That would probably be MUCH faster than calculating all those isosurfaces.
Creating a mesh or a heightfield to do it would be faster still.

I made one with prism bricks with a normal, over a plane with a normal.
I left the 2 points bracketing each [implied] corner unperturbed, but that's
easily changed.

This is what I am using currently. I will keep poking around over the 
next few days.
