I recently shared some Apollo tribute icons that I made. As you all rightfully said, an antenna on a Lemmy app doesn't make much sense! I had another stab, but this time tried some slightly more original ideas, and made something that I feel captures "Voyager". Let me know what you think.
Happy to provide another free download link for this one if there's demand. Also, if you want any tweaks or have any other ideas, please let me know. I could make these all day!
Edit: As people have asked, here's a free download link for the icon and another simplified variant I made based on some feedback. Here's a preview of the simplified variant.
Looks great! Really well done.
