Fabián Orccón contributed and proposed these wallapapers for Gnome 360. They might won’t be included but still is a nice work and many people I guess want to use them.
So we are sharing them!
Only the first wallpaper is proposed for Gnome 360 but I included two more.
These are 1280×800 resolution but Fabian provides also sources and almost every possible size variant for the first wallpaper from his Drop Box.
