I had seen some desktop pictures with floating clocks and other neat eye candy and wondered where it came from. Screenlets has several small programs you can use to spice up your desktop. While I am not using the clock, I am using a weather screenlet and a screenlet that gives me information about my computer (as well as the time).
The screenlets web site lists many of their screenlets (maps, calendars, copy/paste lists, e-mail, notes, etc) and has much better screen shots. I used these directions to install the package. (which amounted to adding deb http://ppa.launchpad.net/gilir/ubuntu gutsy main universe to your third party repositories and then installing screenlets).
After the instillation, screenlets appeared in my menu under preferences. When you start screenlets, it shows you a list of screenlets and allows you to start them by clicking launch/add. Its all intuitive and easy. You can move them to any location you choose no your desktop and increase or decrease the size. While they are transparent, it is difficult to see behind them meaning they may take up some screen real estate. Cool, easy, and information I want at a glance.
