This is my current Desktop
mostly a default KDE desktop with a few useful widgets (CPU, RSS, pastebin, notes, kopete (ICQ, MSN, Jabber and Skype contacts)).
The Wallpaper is a screenshot of OilRush, a game which is still in beta but is already available for linux (native) and has amazing grafics (as you can see; these are ingame grafics).
Most of my desktop icons are games... When I want to code or so, I open my projects folder and use my desktop only to share screenshots (pastebin).
