Hah hah, cheers. It's taken me a decent chunk of my spare time to build, and it's not even half done yet. Going to stick lava in the 4 corners, and add some other stuff. The plan is to stick lava in the 4 corners, for it to light up, then I'll stick water fountains/pools and other nice looking things inside. I actually used Mcmap rather than cartograph because I could never get cartograph to work properly :< Also Mcmap does this pretty cool thing where you can get it to show caves in relation to the surface. Minecart systems aren't as hard as they first look either, just experiment around with boosters and stuff. Just remember that carts with people in gain more momentum than those that don't. Just experiment around/watch videos on youtube to get an idea of how they work. Also, am I right in thinking grass now varies in colour around the map? I thought Notch had just changed the texture colours to make them more browny/realistic, but I was on SMP for the first in a while and I noticed the grass was paler than my SP world.
