A city that I have been working on for a few months. Includes several world famous landmarks such as the Space Needle, the Shanghai World Financial Center, and the Twin Towers of the World Trade Center. It also includes a 50x50 spleef/PvP arena, a fully functional automated minecart system with four stations, and a hotel with 18 rooms. Hopefully I can put this on a server soon.

This isn't mine but its the whole Earth in minecraft its crazy! I uploaded it so i could take a closer look. Unpacked its 1.3gigs! Just see it for yourself.

240 room minecraft hotel complete with a lobby, dining room, theater, disco hall, 3 story under ground mall, pool, train depot and more its 26 stories and each floor takes up 5 blocks. This is my first edited check out the video on YouTube at http://www.youtube.com/watch?v=zNQHbl8ZliE

I started this map several months ago as a castle. Its the tall portion on the left side of the screen shot. I built that entirely legit. Then I discovered MCedit and it exploded in size.

There is lots to explore, red stone circuits and all. I built my house a few miles away from the hotel, you can get there by underground rail or the walking path out the back door of the hotel on ground level.

Its still a work in progress, although I'm kind of getting tired of it,
