Proof by picture: A selection of nice picture proofs

Just like any other cultural group, mathematicians like to tell stories. We tell heroic stories about famous mathematicians, to inspire or reinforce our cultural values, and we encase our results in narratives to explain how they are interesting and how they relate to other results. We also tell stories to convince others that our results are valid, and preferably also to explain why they are true. These stories are what you know as "proofs".
