Slider/Trackbar alternative

Anyone know of a custom control that looks like this Volume control http://img806.imageshack.us/img806/9366/volumecontrol.png and works similarly to slider or trackbar?

I tried googling but all I found was this, w/c is similar to the built-in trackbar control 开发者_如何学编程in VS2008.

I don't use WPF; just C# 2.0.

You might be able to modify the code of this control to do what you want.
