Coup d'Bungie is a script created by CAVX who recently turned it over to Iggyhopper. It is executed through the Greasemonkey extension for Firefox. It can additionally be run through the Opera and Chrome browsers. Through it you have the option to turn off all elevated member titles, bars, all moderator/administrator colors and you can customize your own title bar, user title, post background, text color, font, and avatar. These changes are all local to your computer.
There is, however, a MasterScript, run by Iggyhopper. This way your style can be seen by anyone else running the script. To register into the MasterScript, Iggyhopper must approve the style first, more recently he decided to allow all profile changes to go by without approval due to many good factors.
