i did some research, and apparently this format is officially called “coolyori”, which sounds like “cool yuri”, which is very based.
also, i’ve ditched imagefilp! i found the original meme on knowyourmeme and cleaned it up a bit using pixelorama and krita (it’s perfectly square now, and the dividing lines are pixel-perfect. i also fixed the background, which was very noisy, since that makes it difficult to recolour).
i got the logos from the wikimedia commons.
I’m not annoyed. It’s their platform; they can do as they please with it. I actually kinda like that it has to be FLOSS. Also, it’s non-profit, so that seems like a fairly reasonable requirement.
I’m probably gonna check out Sourcehut at some point—a cursory glance at their terms and conditions seemed to indicate that there aren’t any restrictions regarding project licensing.
