Modular Miniature Building Set

A couple of my friends do miniature gaming, and I found a few websites that specialize in laser-cut miniature buildings and scenery.  I saw an idea similar to this, but I made it so that the whole set is modular.  Panels can be flipped upside-down or broken, and they all interlock with each other and the floor tiles, so there’s a wide variety of different buildings that could be made quickly.
