Have you ever made symbols to represent your world? If not, would you?

You know how IPs usually have logos to represent the entire universe? Would you ever make one for your world or are you fine not making one? I was wondering what mine would look like. I imagined mixing parts to imply both ancient and modern technologies, like a sickle sword and gear. I feel like gears are becoming a common motif in how I imagine symbols for my world, like a gear spinning when moving along the timeline (like when scrubbing through the timeline of a videogame or movie series, \[go to the timeline section of this example for what I mean\](https://zelda.nintendo.com/about/)). Doesn't help I'm currently playing Vintage Story which has a lot of \[gear imagery\](https://i.imgur.com/FkUHHXE.mp4).
