Going around the curve

So the first production piece is to be on the idea of a curve, a piece which visitors to the college can interact with, and is mainly ceramic. I have a number of ideas in mind, but what is interesting is what I do and don't want the piece to be about. Firstly, it can't just be a curve, or about a curve - I immediately thought about a "learning curve" - given where we are. Underlying my thoughts is that I will want the piece to reflect the idea in at least three different ways. If it was a "simple curve" it might have to be tracing the path of a baseball -a curve ball. Also it will have to be something that grows with understanding. Not really sure why, aside from the fact that I have always worked that way, both in my photographs, and that I'm always looking for deeper meanings.
