This is a Node.js implementation of Wolfram's cellular automaton, created by a 12-year-old learning JavaScript. The project demonstrates how to build and visualize cellular automaton rules in a command-line… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I'm 12, learning JS, and wrote Wolfram's cellular automaton in Node launched in 2018; newer entries below may have overtaken it.

   Cellarium: A Playground for Cellular Automata▲41

   Hey HN, just wanted to share a fun, vibe-coded Friday night experiment: a little playground for writing cellular automata in a subset of Rust, which is then compiled into WGSL. Since it lets you dynamically change parameters while the simulation is running via a TUI, it's easy to discover weird behaviors without remembering how you got there. If you press "s", it will save the complete history to a JSON file (a timeline of the parameters that were changed at given ticks), so you can replay it and regenerate the discovery. You can pan/zoom, and while the main simulation window is in…

   Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.

   I'm 17 and wrote a guide on how to build your own programming language▲149

   Hey! I’m JC. I’m 17 and part of Hack Club, a nonprofit where we help teenagers ship programming projects with their friends while growing technically. A while ago, I asked myself the question, “How exactly do programming languages work behind the scenes?” It seemed really daunting until I went to a half hour workshop at a high school hackathon about writing a tree-walk interpreter and realized that getting started was actually super fun. This guide is designed in the vein of that - to get people, especially teenagers, started on learning how to build a programming language in a literal…

    Wolfrominoes▲10

    This is a little puzzle game I made based on Wolfram's rule 30[0]. I was doing some sketches based on old Genuary[1] prompts and for some reason this idea stuck with me, so I polished it up into a hopefully playable state. I wanted to keep things minimal, but as a semi-easter egg you can play custom variants using url parameters like https://demos.samgentle.com/wolfrominoes/?rows=20&rule=110 [0] https://mathworld.wolfram.com/Rule30.html [1] https://genuary2021.github.io/prompts

    AI that generates 3blue1brown-style explainer videos▲93

    I've been building prototypes of new AI learning tools for months, but I recently learned that 3blue1brown open sourced his incredible math animation library, Manim, and that LLMs could generate code for it without any fine-tuning. So I made a tool that automatically generates animated math/science explanations in the style of 3blue1brown using Manim from any text prompt. Try it yourself at https://TMA.live (no signup required) or see the demo video here: https://x.com/i/status/1874948287759081608 The UX is pretty simple right now, you just write a…

    Visual A* pathfinding and maze generation in Python▲135

    I was fascinated reading through another recent HN submission about a highly efficient implementation of A* in Lisp, which got me thinking about how I could do something similar in Python. However, these kinds of pathfinding algorithms really need complex terrain/mazes with interesting obstructions to showcase what they can do and how they work. So, I started thinking about how I could generate cool and diverse random "mazes" (they aren't really mazes, but I'm not sure what the best term is). I got a bit carried away thinking of lots of different cool ways to generate these mazes, such…

    My platforming game written in C 89▲127

    I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…
