Imajourn
We are now on the Apple App Store with multiple new features
What it does
Imajourn is an interactive simulation sandbox that brings the physics of waves and sound to life. Whether you are an artist, a physics enthusiast, or a meditator, Imajourn offers a mesmerizing playground of light, motion, and geometry. Imajourn has moved from its early open source webapp version (Numatics) to a fully functional App Store app with new name and branding, and many new features: Interactive wave sim, chladni patterns and cymatics, audio reactivity, 3D particle sim, presets and more!

I made this iPhone app called "Affine Tuning" which is a collection of body-interactive musical pieces: https://affinetuning.com/ It uses body tracking (Motion Capture from RealityKit) to shape dynamic compositions. The app is completely free and will be updated in the future with more songs and other interactive features.

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:…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
