Tree Dynamics

I recently bought the amazing "elemental magic: The Art of Special Effects Animation" book by Joseph Gilland. As he talked about the dynamics of fluids I thought it sounded quite similar to the dynamics of a tree and I got a sudden urge to apply the theory on some tree sketches. And it payed off ( and I'm only on a quarter of the book), can't wait to experiment further. So thanx mister Gilland!
