To create StatusVol themes, you're gonna need to start with a base directory. In that directory, create "dark" and "light" folders. These folders, quite simply, allow you to have different images for each state being displayed as dark (black) or light (white). While you're not limited to black and white, the status bar elements are generally displayed in these colors.
You'll need to create 0.png (min/off) through 16.png (max). The sizes can be up to:
225 width x 40 height (retina, @2x.png images)
112.5 width x 20 height (non-retina, .png images)
Once your done with 0-16 in both light/dark modes, copy the main directory to /Library/StatusVol. Activate through the Settings.app.
