The system preference application (are sys. pref modules applications?) GeekTool is now available on the Mac App Store, making it one less application we have to manage through manual downloads and updates.
The application, yes we’re sticking with application, lets users customize their desktops in a way that a vanilla install of OS X cannot.
Text, shell script, and terminal commands can all be run from within GeekTool and be placed on your desktop, formatted, and styled in any way you see fit. For a while I had the Macgasm server info on my desktop, including RAM usage, CPU usage, and apache logs. If you’re familiar with command-line-fu then GeekTool is for you. It can do some pretty fantastic things.
Oh yeah, it’s free, so you’ve got nothing to lose by downloading it and trying it out.
