Yes, that's what I wanted to try and tried to avoid - by adding a granite
pigment, I reduced the gradient to something like 22.

Perhaps I'll try that anyways, since I don't like that the brickpattern does
not alter in the z direction. I mean, those bricks are straight behind each
other, which is not, what I expect (but I don't know if they do it this way
in RL). OTOH I could achieve that with a repeat-warp with an offset, I
think.

Oops, thank you! I thought I had set the global ambient-value to 0 as usual,
but it wasn't. Hm, doesn't help that much, I'll have to lower the brightness
of the color a bit.

He takes a bozo-pattern and repeats and "offset"s to fit on the bricks. But
I just saw, that Ken allready posted the link to the tutorial ...
