AutoWallpaper is a cross-platform desktop wallpaper changing utility. It automatically (or manually) changes the desktop wallpaper at a specified time interval set by the user. It runs in the background with a system tray icon that is visible when the application is running. It is written in Visual C# .NET 2008 (Windows versions) and Qt 4.4.3/4.5.0 (Linux/others).
QSynergy is a comprehensive and easy-to-use graphical front end for Synergy. Synergy lets a user control more than one computer with a single mouse and keyboard (and has lots and lots of extra features on top of that). Since Synergy only has a GUI for MS Windows, QSynergy was written to step in and fill this gap for users on Mac and Unix platforms.
