It can deal with rational numbers and complex numbers. It has matrix support as well. It uses the gmp library so it is very fast for calculations of large numbers. It has a command line and a GNOME interface. The GNOME interface supports plotting functions and 3D surfaces.
Inkscape is a drawing tool with capabilities similar to Illustrator, Freehand, and CorelDraw that uses the W3C standard scalable vector graphics format (SVG).

GNOME Schedule is a system schedule maintenance tool. It has support for the cron and at scheduling systems. It aims to be as HIG compatible as possible.

Smuxi is an irssi-inspired, flexible, user-friendly, and cross-platform IRC client for sophisticated users. Smuxi is based on the client-server model: The core application (engine) can be placed onto a server which is connected to the Internet around-the-clock; one or more frontends then connect to the core. This allows the connection to IRC to be kept up even when all frontends have been closed. The combination of screen and irssi served as the example for this architecture. Smuxi also supports the regular single application mode. This behaves like a typical IRC client; it doesn't need separate core management and utilizes a local engine that is used by the local frontend client.
Dreamcard is an easy to use development tool for new and intermediate users. It supports multimedia, Internet protocols, databases, and more.

XDroplets is a set of launchers that better integrate X11 programs with the MacOS X environment. X11 programs can be launched via the Finder or Dock. Documents can be opened directly in X11 programs by double-clicking or drag and drop. URLs can be forwarded from Mac apps to X11 programs. X11 is automatically launched if it is not already open. The distribution includes XDroplets Factory, a utility for generating your own custom X11 launchers.
