Hello, is there a way to make systray notification icons that change for a certain state? Such as the volume indicator, the network indicator, battery meter, etc.

For instance the icon for my network connection (Vista) will show a globe when I have internaet connectivity and no globe (just the 2 PCs) when there is not internet, and it will show an X when the cable is disconnected. And the volume icon would show an X for mute...

I am able to change the icons but they are static and do not change. thanks.
