BlurWal will first generate transition frames for the current wallpaper, with each of them being an increasingly blurred version. When you then open a given number of windows, these frames will be set as your wallpaper in quick succession, giving the effect of a smooth blur transition. When the number of open windows goes below the threshold again, the transition will run in reverse and consequently unblur the wallpaper.
tl;dr: A sleek-looking blur effect for your minimal desktop's wallpaper.
