I built some free open-source digital art software (NOT AI!) to help me make abstract landscape art and music visualizers, here are some of my original works including timelapses showing the process. Link to the tools in the first image description.

Disclaimer: NO AI INVOLVED, just some highschool-level trigonometry and a few years of programming

I'm not trying to make money or anything from these pieces, I might consider selling prints one day in the future but honestly I've just been obsessed with this kind of art since I was a little kid and its been fun finally being able to make some. I've been a programmer for roughly 10 years now and this generative art project has been an on-and-off thing for a few years. You can support my work by following me at https://instagram.com/nafeu.visual and you can check out the software here: https://github.com/nafeu/oavp, it is completely free and open-source, feel free to fork it, open issues and open PRs to contribute. It is built ontop of Processing (https://processing.org/)

Documentation is lacking but I promise if you bug me enough I will update docs and also publish some videos on how to use the software, export sketches, etc. Anyways, enjoy the art!
