Thanks!

Actually, its another instance of heightfield-modeling.  I scanned a 
seed twice--once with white behind and another with a sheet of black 
paper behind it.  In Photoshop, I used the two images to create a 
suitable heightfield, pigment map, and translucency map.

Speaking of--is there a way to use different functions to create the 
various parts of the color vector in a pigment{}?  That is, I would like 
to use one function to control the pigment and another to control the 
alpha.  I know I could do it using a texture_map, but is there another 
way?  It seems like there should be, but I can't think how to do it.

Looking at the image now, it occurs to me that I've done it 
backwards--whirlybird seeds fall with the ridge facing down.  Guess I'll 
have to re-render.
