Not even gonna bother posting mine. I just have a standard Razer background, with the green snake emblem. I like it though, it's very neutral.
No clutter, all I have on the desktop is the trash bin and spur-of-the-moment Notepad files containing various short-term notes of things I need to remember. Not much point making a calendar entry if it's just my sister calling and asking me to check for a movie ticket.
All my quick-access stuff is in folders down on the task bar, which is of course collapsible for increased screen space. My internet browser is the same, all I have extra is my anti-virus / net security toolbar.
