I use it to generate a new wallpaper every time my computer is booted.
though really i just mean changing wallpapers, like https://satelliteeyes.tomtaylor.co.uk/
my thing is a collection of public city webcams from around my state, that get applied to various displays on a cron. i add noise, saturation, etc. sometimes two displays get such a wallpaper that i find the combination lovely

now, this isn't really generative. but i've imagined and toyed with it. splotches of greyscale, or flip that and only splotches of color
i've imagined embedding secrets, whatever that means
