My families LAN world, I started this when our internet was down one day and I couldn't play on a server. And since this world is in 1.3 we can open it to LAN and both my daughters get to come play minecraft with their dad :)
So far we have a nice little walled village in which we each have a small house and so far, a small wheat farm, a chicken/egg farm, a bit of sugar cane and tree farms for the 3 types of trees we've managed to track down so far. We have explored 3 out four directions out to 5000 or so blocks in a straight line from 3 of the gates to our village and will head out in the 4th direction this weekend in search of the elusive jungle biome.
The world was generated using the large biomes option so things are rather spread out and our little home village is centered around a well which sits right on 0,0 in the x and z co-ordinates :)
A little update, we found our jungle in the fourth compass direction and now we have all four wood colours available at home, also you'll see in the new screenshot the girls and I have cut out a large section of hill ready to build a large animal farm :)
Another update: It's been quite a while and now we have a VERY large mob trap which is switchable between XP farming and just mob drop farming. It's the giant sandstone structure on the map.
