Ya reminds me of the dots and dashes we see floating around planets. Like Jorki said - might be good to get snapshots from different commanders and with different ship backgrounds to see if the message changes.Good, so it's not a hallucination. Unless it's a collective one.
I don't think it's Morse either. But it looks somewhat familiar.
Can only confirm that it's in the orange background, it doesn't rotate with the ship.
