  Eigendrum - Draw any shape and hear what it sounds like as a drum▲243

  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:…

  Pornpen.ai – AI-Generated Porn▲711

  Hey HN, I've been working on https:&#x2F;&#x2F;pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results. For comments&#x2F;suggestions&#x2F;feedback please visit…
