I built a ship that has several docked power supply beam ships on it. The power supply beams are kept running with logic blocks. Soon afterwards, I started seeing strange lines appearing in space. After a while, I realized that these were in the exact same pattern as the docked turrets on my ship, and what I was seeing was a projected image of the beams.
I haven't figured out why they appear where they do, but I've seen them at various times throughout the galaxy. I've seen them projected in sectors that are far away from the ship. I built a second ship that also uses a power supply arrangement. They are docked at the same space station, and now I'm seeing both sets of beams projected in space, exactly as they are situated at their docked locations from one another.
