I upgraded my system a bit, and so I had to make a new wallpaper for it: My SystemAntoine Magnien's "Milk"
was a huge inspiration for this, as you can clearly see.
It spreads nicely between pivoted 1600x1200 and 2560x1600 displays.
The downloadable .zip package includes these six wallpapers you see in the thumbnails above.
BTW, if you use (and even if you don't use) a dual screen system - I very highly recommend you to use XnView
as your image viewer, that's an incredible program - and FREEWARE! Check out how good it is!
