well ive made my own wallpapers if anyone's interested, they belong to the Munch's PDF file (manual) u can download from the XBOX website.. i have distiller and so i was able to filter out all the text and stuff, keeping the lovely backgrounds..
the wallpapers are perfect size, they're actually bigger then 1280 x 1024 which is perfect for me and my pc..
i will try and upload them somewhere, sometime and will let u all know in this topic! CYA,
ps. ive put the BG i use on my pc for download at:
