Tabula is a minimal Wayland wallpaper tool which aims to provide a better experience on devices with dynamic monitor ratios like phones.

The simplest way to use Tabula is with a single color wallpaper:

tabula -c ff00ff

For images, you can set the focus point to ensure important elements stay at the center of your screen:

tabula -i ~/pictures/wallpaper.png -f 0.6+0.6
