But will ivy grow on that? Or will it need an actual object to grow right?  I could Solidworks the thing out to try.... But there's another fence that might look nice with ivy... I made it for my Wine and Cheese image... (http://www.renderosity.com/mod/gallery/index.php?image_id=1342007&member)  On second thought, though, it's a bit hard to see in that one... I'll have to dig up the object i guess.
