The picture I'm looking for, I can best describe as a dark mode minimalist depiction of what looked like an airlock door.

I originally found it on Google Image (or maybe duckduckgo image) search, and I recall specifically it had "Metalion"-- or maybe it was Metallion-- in the file name

It was all dark gray, with simple running lines that ran from left to right/top to bottom, and it had a sort of inverted symmetry from right to left-- And where the channels met in the center made a perfect square which was centered around the exact spot that the windows user profile image would rest.

I have tried for weeks to locate based on various keywords-- including the name as I am certain it was called "metallion", "minimialist dark screen wallpaper" etcetc on both GIS and DDGIS to no avail.

I know this is an extreme longshot but I'm hoping someone how there might know what im talking about and be able to hook me up because i miss using something so basic yet perfect for my multi screen setup.

In return I'm posting some of the wallpapers I have found in my unending search for this particular image.
