Hey Patrick and Mark,

I think I happened across the thread you're talking about on the DAZ forums last week.  I tried to pull it up with the DAZ forums  search engine using "*Bremmer" as author and "leaves" in the content field but couldn't find it.  If you remember some other words to add (like "gradient" or any other specifics) you might find it that way.  Good luck and thanks for all the help you guys always provide on the forums.

I'm a physician turned author who writes about sociopolitical issues as well as science fantasy.   Please visit me at www.SavedByScience.com
