CFRS[] Community Demos: Patterns with turtle graphics using 6 commands
Hello HN! Back in 2023, I introduced CFRS[], a minimalist drawing language with turtle graphics, featuring just six simple commands, through a "Show HN" post (https://news.ycombinator.com/item?id=37956065). Since then, I've received a number of creative patterns and animations created using this tiny, esoteric language by the small and friendly community that has since formed around it. In this post, I intend to share some of these interesting creations with everyone to highlight the ingenuity of their creators. If you create an interesting demo using this language, please…
In plain words
CFRS[] is a minimalist drawing language that uses just six commands to create turtle graphics patterns and animations. Designed for creative experimentation, it enables users to generate geometric designs through a simple interface. The project has developed a small community of creators who have produced various visual demos showcasing the language's capabilities, demonstrating how constrained toolsets can inspire creative output.

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:…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…
