Do you usually use your FS (9 or X) screenshots as desktop wallpapers ? I do that often. It's not easy because not only the picture has to look nice, it must also provide clear space for the icons to remain visible.
Anyway, that's the one I'm using currently. I love it because it has nice colors with cool looking plane and scenery, and the sky is perfect for showing my left-aligned desktop icons


The picture is in 16/10 format. Here is the non-resized (1680 x 1050) screenshot if you want to use it for your own desktop too 8-)
