I'd like to propose an addendum to monkeys with typewriters rule: given enough time, a room full of Minecraft fans will build a scale replica of everything that has ever existed, real or fictional. Exhibit A: Hyrulecraft, a painstaking recreation of the entire game world from The Legend of Zelda: Ocarina of Time.
GenGame's got a trailer of the map's alpha release, with footage from dozens of the included areas. Despite added blockiness, it's all surprisingly recognizable and nostalgia-inducing, especially the ridiculously impressive rendition of Kakariko Village, complete with windmill.
If you're interested in giving it a shot, you can download the alpha version of the map here. The team is also running a multiplayer server with the map at 64.79.106.218, in case you'd like poke around with some company. Apparently they've got a whole lot more planned, including quests and dungeons that turn the project from a simple custom map into a full on MMO.
