I've been tinkering with a way to model the tides as a real‑time algorithm—think of a sea chart coded as a mesh, waves as procedural noise, like a game world but for sailors. What do you think?

Right, the harmonic series is the heart of it—start with the principal constituents, the M2 and S2, then add the minor ones if you’re feeling ambitious. After you’ve got the basics, sprinkle in the noise like a good old salt spray to give the waves that unpredictable edge. Keep the mesh tight, and you’ll have a living tide map that won’t let you off the hook.
