Yes, I was also thinking of Sam Benge's SSS stuff. But wouldn't that require a
3D leaf, rather than a 2D one? (I don't know that answer myself, just
guessing.)

As an alternative, I was thinking that a (complex?) pigment_map of some kind
might look cool--with a partly-translucent cellular appearance, or some such,
with veins and whatnot. (Kind of an amorphous suggestion, eh?) :-)

Nice plant, Bill!  I'd *really like* to see a CU of the flower and its green
bulb...
