    The little particles will gravitate to your cursor (or touch location), and can even enter stable orbits if the conditions are right! Mainly an excuse for me to experiment with wasm and WebGL, but it makes for a surprisingly good fidget toy.

    I started teaching my daughter physics by showing her how things actually work - plucking guitar strings to explain vibration, mixing paints to understand light, dropping objects to see gravity in action. She learned so much faster through hands-on exploration than through books or videos. That's when I realized: what if I could recreate these physical experiments as interactive simulations? Lumen is the result - an interactive physics playground covering sound, light, motion, life, and mechanics. Each module lets you manipulate variables in real-time and see/hear the results…

    I built a synthesizer based on 3D physicsfree tier, from $99/mo▲512

    I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it. So far it's been 99% a solo project, with…

    A pretty simple but fun to play with simulator for a concept from mathematical physics called the "2D Coulomb gas". I originally made this for my Bachelor's thesis to create pretty pictures and build intuition but have recently gotten it a fresh coat of paint and better performance curtesy of WebGPU acceleration (ported with liberal help from Codex to get through all of the boilerplate). Play around with it - hopefully read up more on the 2D Coulomb gas because it is an incredibly deep topic research wise.

    Hi all This has been my hobby project for quite a few years now It started as a small engine to serve as a sandbox to try out new 3d graphics ideas After adding many features through out the years and re-writing the entire engine a few times, this is the latest state It currently supports loading models with animations, textures, lights, shadow maps, normal maps, and some other goodies I've also recently added voxel raymarching as an alternative renderer, along with a fun physics simulation :)

    Hi HN, I’m a chemical engineer and I manage logistics at a refinery down in Texas. Whenever I try to explain downstream operations to people outside the industry (including my kids), I usually get blank stares. I wanted to build something that visualizes the concepts and chemistry of a plant without completely dumbing down the science, so I put together this 5-minute browser game. Here's a simple runthrough: https://www.youtube.com/watch?v=is-moBz6upU. I pushed to get through a full product pathway to show the V-804 replay. I am not a software developer by trade, so I relied…
