I want to replace this image on Wikipedia:

https://commons.wikimedia.org/wiki/File:RGB_illumination.jpg

I have already created the lights. The problem I have is the brick wall. 
How do I make a smooth glossy painted brick wall in POVray? All the 
brick wall macros I've looked at have sharp edges.

I am open to using a texture instead of an isosurface. In fact, I like 
this one very much:

Unfortunately, that's not a FOSS image. Does anyone have any suggestions 
on where else to look?

Thanks.


Michael
