I've got a couple weeks off from work, so I'm really going to focus on the Atlantis conversion. There are a lot of loose ends, so I'm hoping that the dedicated time will let me add some order to the chaos.
Here are some pics of a little test build. The minis are either LEGOs or standees from OneMonk's hordes.
The catwalk system works well, though I really want it 2" wide, not 1" wide. Otherwise, it's pretty to look at but no fun to play on. I think the roofs look pretty nice, and the walls are good too.
