After chatting with Bob last week, I think he might have something else in mind. The principle of a round structure (like a tree or cylinder) being more suited to withstanding multiple external forces, compaired to the one or two dimensional forces that a two planed structure ( ie 2X4).
I just can't figure out where he is going with this, but I'm going to guess that it has something to do with the existance of object in a three dimensional world.
Or maybe I should just shut up!
