3RVX is a skinnable volume display and controller. It’s not only an on-screen volume control indicator but also includes hotkeys to take full control of it. The on screen volume displays are skinnable and by default you will find 8 different skins, more can be downloaded from the developer’s site.
To add a custom skin, download the skin, extract, and add the folders inside the Skins directory.
The app sits in the system tray and can be set to launch with Windows. The behavior and display settings are customizable and so are the hotkeys.
It works on Windows 7, Windows Vista and Windows XP
