Ah....this is awkward.  It's not working, but I have no idea why.
Things that are going wrong:
    -When I just show the leaf nodes, they're all in the same place
    -When I show all the nodes, they're overlapping in weird ways
    -The doors are in the wrong places

It could be something as simple as a flipped x/y, or it could be a lot
worse. I need to do other things now though. Like eat.
