There are many "80s anime" and "vaporwave" style loRAs, but I wanted one that specifically does this. It's trained on 30 screenshots (which is every major cut) of Kouji Morimoto's opening sequence for the 1986 movie Dirty Pair: Project Eden and in case you're not familiar with Safari Eyes, allow me to show you the coolest thing you're going to see today. I hope it can replicate even a tiny bit of that style.
It works best with more abstract imagery, such as:
smoke/clouds/fluids
silhouettes
specific bold colors
patterns
close-ups / detail shots
or just letting it do its own thing (but see below)
Known issues:
it likes to add black borders, which is a dataset defect (easy enough to crop out if you care)
you need to prompt at least something it can grab on to, just the trigger is not enough to make a big difference - when in doubt use either "1980s (style)" or "flat color" or both.
