Bwall Is An Animated Battery Wallpaper For Linux (Bash Script)

Bwall (Battery Wallpaper) is a Bash script to use a set of images that show your current battery level as your desktop wallpaper.

The wallpaper is animated while the battery is charging. When not charging, Bwall shows the battery level, changing according to the current battery percentage.

This animated battery wallpaper script supports multiple desktop environments and window managers, like KDE, Pantheon, Gnome, Deepin, Cinnamon, Xfce, LXDE, MATE, Openbox, i3wm, bspwm, awesomewm, Fluxbox, Fvwm and Swaywm.

There are 21 different types of battery wallpapers included with Bwall, and since this is just a Bash script you can easily add your own custom wallpapers.

Besides allowing the user to choose the wallpaper to animate, Bwall also has an option to set the charging animation delay (-d num), which defaults to 0.8 seconds.

As for dependencies, the script only needs acpi for getting the battery and charging data, and feh to set the wallpaper as your desktop background. Xfce users also need xrandr, and for Swaywm you'll need oguri for this to work.
