Common C++ is a highly portable C++ class library meant primarily for the development of portable threaded applications. Support is provided both for POSIX platforms and native builds under Win32. The goal is to provide a truly common C++ framework for writing portable threaded applications that do not require a huge amount of runtime overhead to support, and hence can make C++ and threads suitable even for the development of trivial servers and applications.
Common C++ RTP is an experimental threadsafe RTP stack for use with Common C++. It uses a service thread to both schedule outgoing packets and organize arriving packets. Queued lists of packets are maintained both for sending and receiving, and packet payloads can be mixed such as for passing RTP telephony events. Recent builds of GNU ccRTP are also available for building handheld softphone clients using Open Embedded.
Crossfire is a multi-player graphical arcade and adventure game made for X.

Any number of players can move around in their own window, finding and using items and battling monsters. They can choose to cooperate or compete in the same world.
CTSim is a Computed Tomography simulator. It simulates the process of obtaining x-ray data around a phantom object. It then uses various reconstruction algorithms for reconstructing the original image. It supports animation of projection and reconstruction processes, 3-dimensional viewing using OpenGL as well as cross platform support using GTK and Win32.
