There was a wallpaper I had for so long, but I lost it during a reinstall. It was 3-4 years back so it's pretty vaguely in my mind, but I loved that wallpaper.

It was a dark wallpaper, it was kind of like a brain type of object that covered the entire image, and it was also kind of a planet at the same time.

I doubt anyone will be able to help me, but I'll post some of my favorite stuff.
