As I don’t use FireFox as much as I used to, my whatmon plugin has become less useful to me. (I’m pleased, however, that it is being put to good use by many people.) Instead, I’ve switched to GeekTool, a marvelous program which will display the content of a plain text file, the output of a shell command, or an image pulled from a URL onto my Mac’s desktop. If you want to use GeekTool and need a bit of inspiration, look here for plenty of sexy ideas.
