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.

neko-install-cd is a development tool for modifying System Rescue CD images. It can also perform many other operations. It has a simple interface with excellent inline help. Operations it can perform include: booting your modified image in a virtual machine, burning the original or modified image to a USB drive, creating patch sets from your modifications (using aufs or built-in helper scripts). All of these operations can be performed directly from your Linux distribution, without having to first boot into the system rescue CD as with the system rescue CD equivalents.
The Procrastinator's Timeclock is a simple utility for people who suffer from excessive procrastination or distractibility. The utility achieves its benefits by allowing you to comfortably track just how much time your little "one more thing"s are adding up to and by helping to bolster willpower by providing a gentle distraction from temptations. Its design focuses on simplicity, intuitiveness, and a preference for keeping existing users rather than attracting new ones.
QuickTile is a simple attempt to duplicate the basic functionality of WinSplit Revolution for users who don't like the Compiz Grid plugin.
