Agent Smith, My first thought was of the Simi Valley Area, except for the scale of the rock(singular) and the lake(singular(?) as the 'lakes' are all the same cube?), where I went on a field trip once and learned about something totally unrelated called semi quasi wad (I guess you had to have been there). Any rate the Idea of a train set is appealing. That would make a nice animation if you could keep the render times down. - TJ
