That looks so great! It is very similar to what I am trying to achieve with the node editor random building generator that James has so kindly put together. There are some great examples here. I'm fascinated by the amount of traction Blender is starting to generate. It seems like it's becoming quite a serious contender for some of the bigger software companies, even with their software being "industry standard". I definitely need to learn a bit more Blender, but I just love the smooth simplicity of MoI. It's such a pleasure to work with.
