Hmm, i might have benn wrong about the wood, then. Oh well, there's always Blender. Might be something to explore once i get a bit more familiar withe the Cycles 'mat room'.

i do remember this long thread dating back to 2006, was it? wherein BB discussed this wood shader... which sort-of petered out. No shader, at the end of it.
