I don’t remember ever finding an actice CC art (whether it’s music, photos, videos or anything) subreddit, but Lemmy should be the perfect place for it and would complement FOSS development communities nicely.
update: !cc_art@lemmy.world has been created.
Ai art is cc right? But haven’t seen one that is cc made by humans but there are many art comms tho. But you are right this feels like the right place :D
