last updated Feb 27 2012: https://web.archive.org/web/2020/http://www.minecraftworldmap.com/worlds/7eMrs) and here is a preview of another coming update. My way of saying

Thanks for 500 downloads.

Preview includes a Minecraft 1.2.3 version of a ship in the coming 'Holodeck' update complete with captains quarters, map room, crew beds, many cannons, galley, prison cells, cargo and cargo hold, and more.
