Simple, clean and very usable Visual Style for Windows XP.
m Visual Style for Windows XP, normal & compact start menu. You need to patch your XP installation with UXThemePatcher before applying any third party themes. You can download the necessary files from here.
m Wallpaper. Nature inspired wallpaper to go with the theme. It cames in 2560x1600px, 1920x1200px, 1680x1050px, 1440x900px, 1280x800px & iPhone (320x480px) resolutions.
I strongly recommend to turn on Styler "Clear Type" feature for smoother text display using the smaller font size and to check "bold" in the font option menu. Window drop shadows goes very well with the theme too.
