Cataclysm screenshot from Blizzard is shown above, featuring a look at a part of the Gilnean wilderness. The elven architecture embedded into the tree is very cool. I don't know why, but I always find that sort of growth fascinating. Give trees enough time and they'll move any of our junk out of their way.
