Disclaimer: These are not my images, I simply found them aesthetically pleasing and formatted them for use with ElvUI's new Chat Frame Background feature.
Instructions: Drag and Drop the ElvUI folder into your Addons folder and tell it to overwrite everything. To incorporate this change, you must Restart your client (Exit WoW Completely) and add the following into the Panel Texture Edit Box.
If you have any Questions or Comments about anything within my UI or this download, you are free to post on the comments page, find me in-game (Konungr - US Illidan - <Unleash>) (BattleTag: Konungr#1372), find me on FluidDruid, or at my thread on the Tuk/Elv UI Forums. My preferred method for contacting me for anything related to my UI would be my thread at Tuk/Elv. You can also see my UI in action in my 10 man Progression Feral PoV videos on my YouTube channel.
