Gnome-o-phone is an internet telephone. In other words, if you and your friend have computers with sound cards and network connections, you can use gphone to talk to each other and save on phone bills. Gphone uses GSM compression, so the data rate should be low enough to work over a reasonable modem connection. Gphone supports full duplex if your sound card does.
Gepetto provides a framework to animate characters. It lets you record choreographies and build complex moves using elementary actions. Gepetto is fully graphical and offers real-time rendering of the animation, but there is an undelying textual language describing the moves which can be used directly.
GClipper is a multiple buffer clipboard that automatically fetches new selections and maintains them in a history. It shows a listview with the fetched selections and allows the visualization of their details. The selected row in the listview will be used to determine the data for selection retrieval (paste).
gbrctl is a GNOME utility to configure the Linux Ethernet Bridging code as found in Linux kernels version 2.3.47 and higher, and patched 2.2.x kernels.

fsv, the 3D File System Visualizer, allows you to view a collection of directories and files as three-dimensional geometry. It represents all or part of a filesystem as a collection of blocks of varying sizes, each labeled with a filename, and arranged in a manner consistent with the original directory structure. fsv can visualize any arbitrarily large collection of files, limited only by memory and hardware constraints. Program features include an integrated 2D interface, intelligent camera handling, and extensive use of animation. fsv requires OpenGL.
