I've been making wallpapers for my work computer, that's why the size is 1600x900.
I wanted a "holiday" image of Sailor Moon, but something with the main 10 scouts. I was happy when I found this image in such a large size.
I obviously didn't create the image (original art of Naoko Takeuchi herself), but I did crop it out and create the background. I don't understand why more wallpapers aren't like this: image on right, faded out blank on the left for desktop icons.
Feel free to use for your own desktop.
