Hello HN. This is a project me and some friends built at university in 2017. It was originally built in a rush, but we've added a few improvements over the years. It's a fun game to host at a demoparty and project on a big screen - We did that at Instanssi many times. The implementation is still rough, and suffers from the fast pace of the modern web - The frontend is likely very outdated, and the backend is built with Vapor 2 and Swift 3.1, both no longer supported. You can host this yourself, but it might be a bit of a pain to set up. The WebSocket protocol is fairly trivial to work out…

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
