Of course, now I see it.  Thanks.  I've been going crazy trying to do 
this by changing A, B, and C, and adding a "+sin(D*v)/E" or whatever in 
just about every conceivable place and combination.  (Mike Williams has 
some great pointers on how to modify and combine functions in his 
isosurface tutorial, but none of them were quite getting what you had.) 
  As you say, I did come up with some interesting other "flowers," but 
nothing very realistic.  Simple solutions usually elude me (as do 
difficult ones, but I don't mind those so much.)

Thanks again
