The internal brick pattern in POV won't work radially will it? I'd have to use 
some sort of mapping (image, pattern, etc) wrapped around the cone/cylinder, 
right?

I'm thinking one image (a row of stones) could be mapped onto a cone that was 
just the height of the image and then scale the image around the 
circumfrance <SP?> of the cone for each row, between that and some rotation it 
should stagger the stones and the incline on the cone wouldn't be so steep as 
to distort the image too badly.

Using cylinders would be more accurate, but softening the edges around the 
stones would be a mess, then again, I'd have to test-render it, the hard edge 
might not even show up in a final render.

The bricks on a cone I think I'll just not worry about now, I think I've 
decided on stucco as a finish (once I perfect it), kind of a painted rough 
surface with hairline cracks in it. It's for a lighthouse, many (most) are 
painted brick... Stucco I think would be an acceptable finish for it.
