Proposed: Lemmy.world logo.
(lemmy.world)
Here are some proposed graphics.
EDIT: I've now made a repository on GitHub, so that you can download the graphics and use them for your communities and projects. There's even an Etsy store selling stickers now.
2 & 4 are great.
4 looks like it'd make a good favicon - the shape is distinctive enough that, along with the colors, it should be easy enough to tell apart from other sites' icons when you have a bunch of tabs open.
2 is great for the general icon/logo on the website itself.
