locket is a Dashboard widget that provides an ambient monitor for a single iChat user on your buddy list. When s/he is available, the locket opens. Otherwise, it is closed. Clicking on the open locket will start a new IM chat.
To get a customized locket via email, send Stephan an image for the locket, the default AIM handle to use and the name of the person. The custom widget requires no configuration, though you can change the IM handle and optionally allow the locket to open for “away” and “idle” status.
