window shopping
     
         A term used among users of {WIMP} environments like
        the {X Window System} or the {Macintosh} at the US Geological
        Survey for extended experimentation with new window colours,
        {fonts}, and {icon} shapes.  This activity can take up hours
        of what might otherwise have been productive working time.  "I
        spent the afternoon window shopping until I found the coolest
        shade of green for my active window borders --- now they
        perfectly match my medium slate blue background."  Serious
        window shoppers will spend their days with bitmap editors,
        creating new and different icons and background patterns for
        all to see.  Also: "window dressing", the act of applying new
        fonts, colours, etc.
