I converted my wife to Ubuntu Linux after her Win98 system got hacked. I had fortified that Windows system to the nines for several years and just couldn't hold out any longer. The keystroke logger she receieved was the last straw.
I created this main menu / taskbar theme so that the interface was familiar to her. At first I used a bitmap of the Windows desktop, but then that didn't do Linux any justice, so I came up with this Hopi-indian like symbol.
