First off there is a Starship high above made by myself. The ship is complete with power core, main bridge, secondary bridge, quarters, cannons, galley, captains quarters, 2 cargo bays, and 2 fighter hangers.
Inspired by Star Trek, Star Gate and Battlestar Galactica.

Second is below. An automated Mob arena Version 1 Built by Aracongi with some help from Syntacks. This thing is complex! sleep in the bed near the entrance, flick the switch (mine cart up top will start to circulate meaning it is working) and enter the mob arena. This version is a work in progress but is working as is. fight zombies, skeletons, and cave spiders. There is no exit once in the arena atm.

My first minecraft world, includes:

*castle, with keep, towers,lava moat etc
*A wooden pirate ship with working cannons
*A large TNT Cannon
*~1/3 Scale Iowa Class battleship
*Massive monorail line "Skyway" which leads to
*Huge Watchtower/Fortress/Cathedral
*Also has a pyramid which houses some treasure
*Numerous mines which lead to the bedrock
*Argonath(LOTR) style statue
*Walled city(wip)
*Miles of underground tunnels
*Underground missile base, with working missile launch system

continually worked on since beta 1.2 or so
