Klen-library is a program for creating electronic books. It consists of three modules, for editing books, reading books, and creating tests. It offers password protection of every book and the editing mode. The print function makes it self-sufficient, as it allows creation of books without using third-party text editors. It uses SQLite, so you don't have to install a database server. It can export to the XWB, HTML, TXT, PDF, PostScript, and RTF formats, and can import from XWB, HTML, and TXT.

Emergent is a neural network simulator with a built-in scripting language which allows for the creation and analysis of complex, sophisticated models of the brain in the world. Networks and all of their state variables are visually inspected in 3D, allowing quick "visual regression" of network dynamics and robot behavior. Emergent is a direct descendant of the PDP and PDP++ neural network packages.
Artha is a handy thesaurus based on WordNet with distinct features like global hot key look up, passive desktop notification, regular expression based search, etc. Artha may be used as a free open-source replacement/clone to the proprietary WordWeb Pro thesaurus (which is also based on WordNet) on Unix-like and Windows operating systems.

Raggier is a plugin-based raytracer that supports XML format scenefiles, POV-Ray, and Polyray scenefiles. Other facilities planned include Lindermayer Systems (L-Systems), AVI/OGM (Ogg Vorbis)/Matroska animations, and a Perl/PHP Web interface. Raggier uses the Libtrace library, modified with various fixes to get it to compile using gcc 3.x and to improve the results. The modified version is called LibTraceMod and is available in the CVS.
