Nice one Mike, I've got that same banner up in my room. This is what I've had on for a while - stole it from the Gallery here. Hope the owner doesn't mind..
For the longest time it was just a silver icon on a black background. But ever since the girlfriend had her self a photo shoot it changes every five seconds (literally I have mac and use the change background feature lol) and borders upon explicit.
Got to love personal computers :)
Got to really love Macs :)
