Check out this epic creation titled "Pirate Rock" by Fraslund.
This has some seriously cool rockwork and architecture, and has been blogged at least twice elsewhere. It was originally going to be an entry for CCCXI, but he ran out of time to finish it before the contest ended. I'm glad he didn't, because A: My puny entry to the same category would have been utterly crushed, and he says if he had decided to enter it, he would've just thrown together the last parts and left it not as glorious as what we see here. I'm glad we get to see it in all its glory.
