Some people wanted the apple and windows logo from the wallpapers as PNGs. Here they are.
PNG images are 128x128 and 256x256.
These icons are for personal use only. You can use these PNG images for your personal websites, blogs, as avatars, signatures or display pictures on forums or instant messaging software. Dont release these PNG images as your own or part of an icon set, wallpaper, etc.
