The GUIShell project is a collection of utilities facilitating the use of the GTK+ toolkit in shell scripts through the gtkshell utility. The ACE configuration environment provides sample scripts utilizing gtkshell for desktop utilities. rootcat provides the ability to display messages to the root window using Xft, allowing one to write status display scripts.
Voody Blue Subtitler is a suit of programs that allows you to manually synchronize a text file with a video stream, thus creating a subtitles file. It consists of a master client (to do the sync), a slave client (projector), a relay server, and a configuration utility. It runs on Linux and Windows (all except the relay server), supports video output via GStreamer (Linux and Windows) and MPlayer (on Linux only), and supports GTK+ 2 and 3 (decided at compile time).
isymchoose can automatically determine which symbols (functions, types, enumerators, etc.) are available in a given C language source file and present you with a list of completion possibilities, including return types and argument lists. With a little help, it can also display documentation for symbols. At its simplest, it functions as a keystroke-economical, context-sensitive symbol completer. However, additional features exist that aim to let the programmer remember in general, fuzzy terms what their libraries can do and quickly find and insert what is needed, rather than having to remember or awkwardly look up exactly what everything is called, what arguments are required, etc.
Gswitch automatically changes your GNOME desktop background every so often. The backgrounds are displayed randomly. All background images and style settings are sourced from your list of backgrounds as configured in "System > Preferences > Appearance". By default, images are switched after 20 minutes. Although the images are shown randomly, every image will be shown at least once before you see any repeats.
checkcopy is a GUI tool to copy the files and directories to some destination while creating checksums and/or verifying them. It reads all the checksum files, then reads in each file to copy it to the destination. If a checksum is present for the file, it will be verified, otherwise the checksum is written out to disk.
