(this is the most beautiful one yet. originally i thought these would play out to be purely ornamental, but i'm starting to get used to having a unique "identifier" per terminal session and notice myself scrolling all the way up to check if i got the right tab. also wondering if terminal sessions have an inherent unique ID of some sorts that could be used as a seed for these identifier images. update: they do! `echo $$` outputs the pid of the current session.)
