For my server, I now generate two maps every four hours, one that's just a top-down map (with c10t) and an isometric map (MCmap):
If you look down a bit from the center of the map, you should see a glass tower, and then some buildings. The big wooden house is on a large overhang, though you can't really tell from the map. Canadave
's house is down below my wooden house, and to the left of the glass tower.
There is also a "bridge to nowhere" near the lower-left corner that I have no idea who built or why.
