I love your background picture: Robots ask for banning captchas. They can not get in 🤣. I say: Replace cloudflare captcha guard with anubis btw.

Yeah, I've got a Metalcore phase currently, but it's getting late, so i'm switching to Diary of Dreams to cool down 🤘

Neither, it's a scene for a program called Wallpaper Engine, which is available on Steam for Windows (where i used it before). The Program itself can still be used to download Wallpapers (which is a simple subscription in the Steam Workshop), but the background service which show the wallpapers doesn't work - but there are KDE Plugins that are able to do that job. They are not feature complete yet, and a few wallpapers might crash your desktop, which must be fixed by editing ~/.config/plasma-org.kde.plasma.desktop-appletsrc by removing the offending entry:

[Containments][1][Wallpaper][com.github.catsout.wallpaperEngineKde][General]
<some stuff>
WallpaperSource[$e]=<remove the path here>
<stuff>

But most wallpapers work fine already!

This one can be found here and the previous one is here

Many are also interactive, reacting to audio or mouse movement.
