Artists on creative platforms designed exact replicas of desktop hardware to use as icons. For instance, custom file graphics matching physical computer cases were published and are still viewable on the DeviantArt Alienware Predator XP Icons Page .
Icon files from that era generally carried the .ip (IconPackager) extension rather than standard raw .ico or .dll libraries.
