This is the XWidget version of the Steampunk Volume widget that you could certainly use on your desktop. It is a lovely piece of eye-candy as well as being useful on your desktop. This is one of a small set of icons/widgets for your desktop, the others are a typical set of Victorian desktop acoutrements. You can control the volume level of your PC desktop by moving the slider or clicking on the mute button. Double-clicking on the widget will cause a personalised Windows application to fire up. The first time you run it there will be no assigned function and so it will state as such - then it will pop up the preferences so that you can enter the command of your choice. The widget takes command line-style commands for windows.

The widget functionality is self-explanatory, tinker with it and you will soon get to grips with it, you can't do any harm. Think of it as a bit of steampunk eye-candy with a useful function.
Click on the slider and drag it to the left or right and the system volume will increase/decrease.
Click on the mute button and the system sound will mute.

If you change any of the system's sound settings using any other tools the widget will detect this and make changes to the slider accordingly.
It can be resized as you wish.
This widget and the others like it will spruce up your desktop and give it a bit of Victorian class. Full instructions can be found here:
