Show HN: I built a synthesizer based on 3D physics (🔥 Score: 155+ in 2 hours)

Comments: https://readhacker.news/c/6tQ9L
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 (awesome) contractors brought in for some of the stuff that I'm bad at, like the 3D models and making instrument presets/videos.
The official launch announcement video is here: https://www.youtube.com/watch?v=NYX_eeNVIEU

I've kept a fairly detailed developer log about my progress on the project since October 2023, which might be of interest to the hardcore technical folks here:

Back in the old days, people used to do general-purpose GPU programming by using shaders like GLSL. This is what inspired NVIDIA (and other companies) to eventually create CUDA (and friends).
This is an implementation of GPT-2 using WebGL and shaders. Enjoy!
