I don't have pics of it since I'm at work but I built a sort of Noah's Ark floating around in the sky where there's a functioning village at one end of the deck, crew quarters at the other, and the central deck is all glass on top so that I can farm animals and trees in the hold below. There's kind of a spire in the middle of the deck too which has a water source at the top and a cascading waterfall that goes all the way down into the hold where it provides irrigation. And you can reach the ark by boat using an aquaduct network I built around it.
