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:…

(TL;DR: http://i.imgur.com/LuPHqiN.png) While digging around in drawers that hadn't been touched for decades, I found a wonderful piece of history.

It worked! It could browse the Internet[4], send/receive text messages[5], make phone calls...[6] The onboard browser even passed Acid1[7,8] and could do some level of JavaScript![9] Unfortunately, most websites…
