more of a dome i think ![Tongue :P](http://www.tekforums.net/Smileys/teksmileys/tongue.gif)
Im helping too, now that I have my triple towers up.
Once it spans a suitably stupendous amount of land Im pondering putting walls down around it encasing everything inside in a pseudo cave/dome
Its actually 1 block below the max to allow things like torches and chests to be placed on top.
Its classic walking around underneath and occasionally coming across people bent over double backwards looking up at it
