From the developer:
Chatlet is a tiny application that helps you use Facebook Chat right from status bar. You will always get notifications whenever there is a new chat or message. The program has a simple and clean interface and allows you resize the chat window to get more space on your desktop.
You may want to check out more software for Mac, such as TweetGlide, Showit or Facebook for Adobe AIR, which might be similar to Chatlet.
