I saw this yellow building fabricated (won't call it built, maybe "assembled") I think it's a bunch of panels over a steel frame. It will blow away in a storm I feel. It's got a nice yellow color though that stands out in the landscape. It's nearly as simple as a model can get, but large enough and with enough interference from trucks and powerlines to keep me from working on it for some time. It's finished and uploaded, awaiting review.
