Whatever's available, heh. I've played on AC's the most, so far.
In a sharing mood, I present this little(ish) thing: Junglehome One, plus a little, done in classic patched-together-screenshot fashion. JHO was the jungle base in Acperience's server, a couple maps back, with a little extra work done to it since I've been using it as a main SP world. I love building in the jungle, yeah.
The obsidian house was AC's, th'gold one mine. The most of the smaller ones were/are NPC rooms, and the larger two were ones folks were hollowing out to make their own lil'houses from, before maps were switched.
The platforms in the upper left lead off toward the top straight tunnel and a surface route, as well as the mushroom farm I put up some pics of earlier. The door over the lava is the end-point of the more...
fun route to get to JHO from the waystation. Of the two platform/tunnels going off the bottom of the main building, the left one leads to hell and the right out into the jungle. The other top exits leads mostly to the jungle, though the furthest right is very close to what looked like someone's hellflooding project before I co-opted it to make obsidian. You can see some of the water in the very far right, heh.
Here's the world viewer pic. I just noticed one of the floating islands got hit by a meteor. Gonna' have to check that out soon-ish
