title: Are there any good metaphors for explaining project complexity to a non-programmer?
body: <p>It was just mentioned that I'm "not exactly building the Sistine Chapel."  This is true, but I am building a freight management application, which isn't exactly as simple as drawing controls on a form (even though the vendors would have you believe it is).</p>
  
  <p>I don't hold this against the person who said it, but I do feel the complexity of what I'm doing is a little misunderstood, or that statement would not have been made.</p>
  
  <p>Are there any good metaphors which might illustrate a project's complexity to non-programmers?</p>
