PS: Could you describe what sort of mathematical arguments you are looking to explain? Who are the target audience? One thing that may be useful: take a look at Prof. James Robert Brown’s lecture on “Proofs and Pictures: The Role of Visualization in Mathematical and Scientific Reasoning” at the Perimeter Institute, where he discusses ways to replace induction-based proofs of some well known theorems with geometrical sketch proofs.
