StreamMonitor is a plugin for GlowWorm FW that organizes and displays incoming and outgoing socket data in a tcpdump-like format. The interface shows the current offset, the data in both hex and ASCII, the direction of the data (incoming or outgoing), packet size, end point IP addresses and port numbers, and more.
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.
