Facebook Status Update Notifier
This will display Facebook status updates right on the Windows desktop. It uses a semi-transparent window to display the unread messages, pokes, friend requests and invites.
The Facebook status notifier uses roughly 1.5 Megabytes with the transparent window open and the main application window minimized in the system tray. The software program requires the Microsoft .net Framework (not mentioned which version). It can be downloaded from the Google Code project website.
