StreamMonitor is a plugin for GlowWorm FW that organizes and displays incoming and outgoing socket data in a tcpdump-like format.

DesktopLyrics is an application that displays the lyrics of the song currently playing in "iTunes" right on your desktop. The lyrics for the song have to be set in iTunes; DesktopLyrics does nothing to fetch them if they aren't available in iTunes. If you don't want to set all your lyrics manually, you can use an application like "Harmonic".
SOGo is a very fast and scalable modern collaboration suite (or groupware). It offers calendaring, address book management, and a full-featured Webmail client along with resource sharing and permission handling. It also makes use of documented standards (IMAP, CalDAV, CardDAV, etc.) and thereby provides native connectivity (without plugins) to many clients such as Microsoft Outlook, Apple iCal, the iPhone, Mozilla Lightning, and a plethora of mobile devices via SyncML. It can reuse any existing email and database infrastructure, avoiding long hours of site restructuring.
SmartMines is a minesweeper game for Mac OS X (Tiger and above) with a few features that make it stand out when compared with many other minesweeper games. For instance, it features "smart clicks" that make it easy to both mark and uncover with single button mice. Also the minefield window is resizable, so actually hitting the square you want will not be the greatest challenge.
NSFileHandleExt is an Objective-C extension (Cocoa/GNUstep) for the NSFileHandle class (which handles files/sockets). This extension provides support for much easier network programming for protocols like HTTP, IRC, telnet, etc. (everything that sends messages in lines suffixed by \n).
Phage is a two-player abstract strategy game. It is somewhat similar to chess, in that each player has different-looking pieces that move in different ways. A game of Phage is finite: there is a fixed upper limit on the moves that can be performed, so games are usually quite short.
