The Plasma 5.2 wallpaper, 2560x1600
Meatloaf the story:
This was originally made as a personal wallpaper entirely for myself. I had a higher resolution monitor than the standard wallpaper provided, and using the Breeze palette I made it for my exact resolution. During the Plasma Sprint in 2015 I was asked to give the wallpaper to be the new default, and we decided that every release should get a new wallpaper so many screenshots would help us identify the Plasma version running on that system for bug reports.
