I'm not sure it's clear what those shapes are, but basically these are big pieces of metal, most likely from a ship that has been shaterred for x or y reason. It felt clear when I did it but well, I wrote the thing so I actually don't know; not that knowing all that is really essential but well in case you did want to know here you go.
Huh, maybe it is just me watching too much sci-fi, but I thought that was a stealth ship with a cloaking device on. Like it is invisible to radar and scan equipment, but if it gets too close the eye can see distortions created by it.
Sinus is working as a Sky Cleaner, wandering around in space to localize garbage for it to be collected. They're living a peaceful routine, not changing much while time goes by, until one day they would be at the wrong place, at the wrong time.
Light SF one-shot featuring Sinus the sky cleaner, space, coffee, as well as not great people, not an AI, and definetly not a fish.
