I don’t have it linked in the header but I’m also proud of https://curves.xargs.org, a visual explainer that (hopes to) give you an understanding of elliptic curve key exchange (ECDHE).

That's really slick, one of my favorite animated diagrams is the generic Fast Fourier Transform animation, and this definitely scratches that same itch. As someone who's horribly bad at math and visualizing this stuff, thank you!
