Po' thanks for offering me your help...
Well, you can take a look at my current preview:


The actual docklet is (in it's preview stage) at
Network Monitor Docklet PreviewOf course those are not my icons, they come from Domesto's deviantart site. I tried to contact him to ask for his permission to use the icons a couple of weeks ago, but although I sent him several messages I was never contacted back.
The thing is that I need an icon that would send the feedback of tranmiting information to the user (in my docklet I changed the original icons to update in bright blue & bright green whenever data is transmited through the network adapter (The icons resemble the windows network icon that rests in the tray area). Something like this would suffice... but you are the real geniusses with icons... I am just a rookie docklet programmer.
Looking at my docklet, under the icons folder there are a few images that I programatically combine to create the animated effect of activity.
