That is my "desktop". Obviously minimalistic. Perhaps a tad too minimalistic. (Click me)
Or, if ompldr is down, here is an ImageShack link: Click me
At any rate, the stuff you see on the top is "xmobar". It lists desktops which have at least one open window on them on the left, then the active window name (which is not there because there is no window on my desktop), followed by CPU and RAM statistics, up- and downloads and MPD, which is pretty much just info about which song is currently playing, written down in "Artist name - Title (Album) [Time remaining]" and, last but not least, the date and time.
The rest is for my window management, done by xmonad. I just LOVE tiling window managers, and doing everything with my keyboard.
Why do I have it this way? Well, because I like it, obviously!
