I am open for suggestions / designs.

AI is very confused by my request and I'm not sure it actually knows what a lemming is.

You could hold an icon contest.

A few communities I'm in have been going with the theme of lemmings dressed up or doing something related to the subject matter. So how do we do that for a whole world?

A world actually made out of lemmings sounds far too gross.

Edit: Maybe he's holding up the globe, Atlas-style? 🤔

nooo, the icon was one of the things that drew me to .world

i don't know whether it's original or taken from somewhere, but it's so glossy and nice

flat design has always been boring, but it's starting to become unfashionable as well

Idk, I think flat design is for the big corporate entities who want to alienate the design as much as possible (windows icon became only 4 one-color rectangle for example). It's not a problem if you are different from the flat-designers. Just be creative.

Suggestion: Globe in the center and a circle of lemmings (like from the classical game) holding hands all along the circumference?

It does look a little dated but I kind of like it that way. Reminds me of "the good old days"™

Yes, I vote for a flat earth icon

Strongly agree with this observation!
