I have Vinyl as my iPod wallpaper, RD as my laptop wallpaper, Colgate as my phone wallpaper, custom Fluttershy ring/texttones, Pinkie siren as my alarm, and Flutteryay as my system sounds and Steam message sound.
I also have Desktop Ponies/Desktop Chubbies, an animated RD Firefox persona, over 400 pony icons, over 12k pony wallpapers, a Luna Chrome Theme, and I am also wanting a way to change Safari so it can be ponified and not the bland silvery color.
