I finished it! Here's the Particle Simulator version 1.0.0: It has a built-in manual and a bunch of presets to help you get started. The code is completely open, the link to it is on the project page.

Of course the project is somewhat raw, and there may be occasional bugs and crashes. I'll be happy to fix them if you tell me about them :D

Already published 2 bugfix releases, ha-ha.

As anticipated, this will likely contribute to substantial loss of productivity and/or sleep. Here just changing the charges of the "salt" preset (and the camera zoom, I reckon) Great work!

Cool! I use @dvs1444 's molecular dynamics simulator for some computational assignments in my class. This looks like it will be great for more complex systems.

Whoah! That's remarkably similar to this thing I made 12 years ago in Java

This is really cool. Thanks! Compiled and played with it.

Yes! Been following for a while, there was a need for this kind of thing in the classroom. Looks clean! Will report back when I get to my PC. Congrats

WoW, NICE!! Must be great for quasiparticles!

i watched gemma 4 12b build something genuinely impressive today, and then loop itself to death right in front of me. the full run is in the video, sped up but completely uncut, watch it to the end and you will catch the exact moment it stops building and starts looping right in the middle of the work. the task was clean, build a single file gravity simulator, n-body physics, orbits, collisions, running locally on one 3090 through an agent. and for ten minutes it was a joy to watch. it reached for a symplectic integrator on its own, the correct one, the kind that keeps orbits stable instead of spiralling out. real gravity with softening, proper orbital velocities, momentum conserved on collision. the physics was right. the thing actually worked. then on the very last step, writing a few tests to prove its own code, it fell into a loop. not a crash, a loop. it started repeating itself and would not stop. ten more minutes, thirty four thousand tokens into a single answer, the same fragments over and over, until i killed it myself. so it's not that gemma can't code. it did the hard part beautifully. it cannot finish. it cannot hold a long task together without unravelling, and finishing is the entire job in agentic work. here's the part that stings. i run this exact task, same harness, same card, on the chinese open models, qwen especially, and i never see this. they build it, they test it, they stop. every single time. google has the raw capability, you can see it sitting right there in the code, and then the model loops itself to death on a task a 27b from alibaba finishes clean. open weights, apache 2.0, so much to love on paper. i just need it to know when to stop talking.
