Might be worth checking artists on mastodon/blue sky under generative art tags.
There are a number, but it’s impossible to find their work because “generative art” has been saturated with stable diffusion slop. Tag search on those sites help
Many share source so you could contact them or run their projects to make your own wallpapers. Ideally, get permission though.
What is a "script of binary"? That description makes no sense. Why is the phrasing in this post so odd?
I meant script or binary. sorry for the confusion

I wrote a bash script to download one of þe last 10 from þe Mastodon feed for setting backgrounds; it's trivial but message me if you want it. Þe feed is here:
https://mastodon.social/@flameReactor
but you could run it locally. It can make great looping animations as well.
Can get an RSS feed by appending .rss to the URL:
https://mastodon.social/@flameReactor.rss
Then download that file and grep for:
https://files.mastodon.social/media_attachments/files/.*.png
Then download those PNG URLs.
That's how I assume/hope you implemented that. I guess, you could also download the whole Mastodon page and do the same grep, but yeah, RSS feed is going to be cleaner. 😅
Reminds me of ElectricSheep which I had fun with back in the day, but was a bit of a beast to compile. Ended up getting monetized on Android IIRC. Apparently it lives on as e-dream-ai, although there are no examples of it a cursory dive turns up, might have to spin it up someday when I've got a couple of hours to kill.
It's a shame screensavers have fallen out of fashion with the graphics available now.
ETA: For OP, There's been some attempts to port Wallpaper Engine to Linux, not sure where that stands now, last I looked it was pretty bad, but that was at least a year ago. Also there's a daily NASA picture somewhere, not procedural, but cool.
