That's very cool! Been meaning to do something like that for ages but never have gotten around it. MOAR!!
Small update on the main module of the LV-426 project, added more stuff to the roof, still needs few panels and stuff. The beams on the side is my own creation, the sides are different in the movie, but I though this would make it look more 'industrial', the modules are like building blocks that are dropped to colonies.
This is hastily sub-D'd so it looks more roundish at some points as it will in the finished thing.
