Allegro is a multi-platform game library for C/C++ developers that provides many functions for graphics, sounds, player input (keyboard, mouse, and joystick), and timers. It also provides fixed and floating point mathematical functions, 3D functions, file management functions, compressed datafile, and a GUI.
Glt is a library of C++ classes and routines for programming interactive 3D graphics with OpenGL. The aim of Glt is to augment the OpenGL API with convenient mechanisms for manipulating the OpenGL state machine. Glt is a work in progress, and by no means covers the entire OpenGL specification. However, it already includes several useful classes and is designed so that additional classes can be added easily. In addition to Glt, the GlutMaster classes provide C++ wrappers for the GLUT API.
Hasciicam makes it possible to have live ASCII video on the Web. It captures video from a TV card and renders it into ASCII, formatting the output into an HTML page with a refresh tag or in a live ASCII window or in a simple text file as well, giving anyone that has a bttv card, a Linux box, and a cheap modem line the ability to show a live asciivideo feed that can be browsable without any need for a plugin, Java, etc.
kmamu is a shell script which installs X icons for xmame into a folder on your KDE1 or KDE2/3 desktop. (These icons can be downloaded from the homepage.) When installed, each icon has a long description name as provided by xmame -listgames, and when clicked it will launch xmame with the appropriate game. Although the install script is specific for KDE, the icons are stored in X pixmap format and can be used with any window manager.
Obsequqiuem is a network-based streaming MP3 jukebox that uses RTP/Multicast (RFC 2250) or Icecast to stream the MP3s. The Web interface allows local and remote users to control what music is being streamed by the server, and includes support for browsing the music collection, playlist mangement, multiple channel support, and an automatic music selection mechanism called DJ Random. The package also includes scripts to do one step ripping, encoding, and submission into the database. The server allows remote MP3 check-in/check-out and a supplied script allows downloading a playlist from the server into a Rio player.
PLIB is a set of libraries to write games and other realtime interactive applications that are 100% portable across a wide range of hardware and operating systems. It's used by Majik3D, FlightGear, and others, and includes libraries for GUI widgets, sound replay, geometry, scene graph, joystick, and fonts/text.
