    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…

    Had some fun with shared array buffers over many months of free time. Skip to the end to play around with the final app. Open to ideas on how to simulate more whilst staying in js land.

    Neural CAs model self-organizing pattern formation. Now they can generate patterns at HD resolution in real-time, enabled by turning each CA cell into a Neural Field. Try 3 demos: grow a pattern from a seed (and damage it, it heals), synthesize PBR textures that can regenerate, or create 3D textures like clouds.

    Hi HN, when learning Golang (and topology), I ported a simple GOL in C (https://github.com/Jeadie/GoL) into Go. I then added a bunch of features - Playing on other fundamental polygons (https://en.wikipedia.org/wiki/Fundamental_polygon#Examples_o...) - Considering all possible update rules (of which, there are many). Looking to get back to this project soon. Would love some feedback + ideas.

    Neural CAs model self-organizing pattern formation on grids. Now the grid is gone. Each cell is an agentic particle that can move freely in space and change its state. While each particle follows a simple shared rule, many together can grow complex morphologies or form intricate patterns. The resulting particle system as a whole can regenerate from damage and exhibits surprising emergent behavior. Try cutting the lizard and watch it heal itself!

    We built an ant colony simulation as an internal hiring challenge at Moment and decided to open it up publicly. You write a program in a custom assembly-like (we call it ant-ssembly) instruction set that controls 200 ants. Each ant can sense nearby cells (food, pheromones, home, other ants) but has no global view. The only coordination mechanism is pheromone trails, which ants can emit and sense them, but that's it. Your program runs identically on every ant. The goal is to collect the highest percentage of food across a set of maps. Different map layouts (clustered food, scattered,…

    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…
