you could pick a random file from folader in a bash script... something like this:

RANDOM_FILE=$(find "$SOURCE_FOLDER" -type f | shuf -n 1)

I used 2 wallpaper applications to achieve this, swww and swaybg

1. For Niri, set layet rule

layer-rule {
    match namespace="^wallpaper$"
    place-within-backdrop true
}

2. Spawn at startup with niri swaybg -i .local/share/backgrounds/paint-blur.jpg &
3. Independent of niri use swww to set wallpaper swww img .local/share/backgrounds/paint.jpg

Hope this helps

The theme is made from colors from wallpaper manually. i used https://pinetools.com/get-colors-image to get the colors and then made the theme

dots added in original post

Battery (visual on charge level and tool tip gives details) Wifi (show signal strength visual and right click launches nmtui) Volume (scrolling increases / decreases volume, right click launches pavucontrol)

Posting dots in a couple of hours

Sure give me sometime and i'll post my dots

its a different workflow, takes a bit to get used to. Since you use KDE look up karousel plugin, you could test out the scrolling work flow in KDE and then install Niri if you like it

yes

did you mean rounded corner of windows? thats niri, in config.kdl

window-rule {
   geometry-corner-radius 8
   clip-to-geometry true
}

plain ole css, border-radius

.modules-right {
	background: @background-alpha;
	border: solid 1px @foreground;
	border-radius:25px;
	padding:0 20px;
}
