If i had been keeping all of my desktop pictures for all of the 'post your desktop' topics, i could've have a slideshow of 'em set to 'Call On Me' because of how similar my desktop icons, taskbar colors, and open windows have been over the years
The biggest difference my desktop has ever seen was back when Vista was still new and Halo 3 was on the horizon because i had a Halo theme that made windows all green and Halo-y and i had a couple of other icons in a second column next to the first set of icons
