Re: wallpaper, alrighty ive made a couple of larger versions 1920x1440 and 1920x1080 (they can be scaled down to fit pretty much any desktop)
+the widescreen version is a bit of a cheat, i just cropped the large 4:3 shot, but it still looks good.
Ive packaged them with a few older desktops of mine:
