If you like this, there is a whole book full of visual proofs [1]. See also wikipedia [2].

A few years ago I re-drew a bunch of these in latex with my PhD advisor and another colleague [3]. We planned to print them as posters and hang them for a Pi day event that unfortunately never happened because the pandemic broke out.

There are full books on these called "Proofs Without Words". On my wishlist. :) https://amazon.com/dp/0883857006
