In this screen cast I demonstrate three scripts I have developed for setting my custom desktop session’s wallpaper.

sbg is a CLI tool that accepts the path to a single image file as an argument. All it does is set that file as the new wallpaper.
sbgmenu is a dmenu interface with two modes: (i) viewing images, (ii) setting a wallpaper. Everything is still text-based.
nbm follows a graphical approach. It presents an image grid where the user can enlarge an image and mark the one intended as the new wallpaper.

All scripts as well as the entire desktop session are part of my dotfiles.
