Dude, I just went to a customers house to look at their leaking basement window yesterday. The entire basement was a scale model train set. I'm talking he had Penn Station, NY and Philadelphia, a figgin circus with working ferris wheel and rollercoaster. It was entirely in a 50's era trainset. The thing was massive and so unbelievable my jaw dropped.
Yeah some of the stuff people do is insane. I have to say mine looks really good, about half way done with my project, but some people are at an entirely other level.
