Safari "metallic" style interface.

Hi guys,
Im new here... and Im not a monster in AppleScript 8)
Does anybody know what is the easiest way to create/use Safari “metallic” style interface in an AppleScript application.
Ive checked InterfaceBuilder... and didnt find it there…

Thank you for you responds.

You must look better!
Select a window and go to the Attributes pane (command + 1). Look for and check “Textured Window”
