I just finished watching the (only) season of Commander in Chief, a TV series from 2006 where hollywood hottie Geena Davis plays the US Vice President who fills the President's role after his sudden death. Geena won the Golden Globe Award for Best Actress – Television Series Drama in the year this ran. I noted that in many scenes during the show (and it's counterpart, The West Wing) always had computers in the background with official desktops and screen savers and the like. I whipped up my own 'presidential' seal for my own desktop, in case I ever needed to look all official and government-like.
