I've added a PlayStation 3 skin as well as an easy way of switching between them on the fly.
Simply click on the Xbox logo and you'll be greeted with a dropdown with options for both Xbox and PlayStation. Then, select the option you want and the skin changes automatically.
I'll have to redo the Xbox controller skin at some point as well as add other skins, such as fightsticks and retro controllers.
Hopefully, for those of you who prefer to use a PS3 layout, this new update provides you with a damn fine looking controller ;)
