Thanks, again.  Now having rendered it, that's just what I'm looking 
for.  I'll need to play with the textures, thickness, etc. for my own 
purposes, but this is a great start.

Now that I rendered it, I see what you mean; I'll want all my grain 
going the same way, but, as you said, that's easy enough to adjust. 
Usually to get a good grain, I remember that it goes along the z-axis, 
and rotate no more than 10 degrees in the x-direction, and leave y 
alone.  But then, I'm a neophyte at wood; I mostly just use the 
"woods.inc" textures.

I tried your shingles. As other said, reduce the rotations, in shingles, 
the grain is mostly along the lenght of the pieces. ADD some tranlation 
to the pattern as all shingles come from different parts of the 
originals wood pieces.
My test with rotations under 5 degre and random displacements gives good 
results.
