SPINA is software for determining constant structure-parameters of endocrine feedback control systems from hormone levels obtained in vivo.

WordBash is a Wordpress clone written in Bash, the GNU Bourne-Again SHell. Everything is generated and output by Bash. No AWK. No SED. No TR. It is all Bash (with one exception). It is a CGI script with an attempt at an OO-like design. It currently supports posts (categories, tags), comments (with spam rejection), themes (true templates), and code highlighting as an administration addon. The current script size is 21 files of about 2500 lines and only 44 kilobytes.
Asymptote is a powerful descriptive 2D and 3D vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications.
beaTunes is an iTunes companion app capable of automatically analyzing your music collection to help you build better playlists. It analyzes BPM (beats per minute), silence at the beginning or end of a song, and the color (based on frequency spectrum) of a given song. Some of the data is stored through iTunes, and some is stored by beaTunes itself. beaTunes can suggest albums that would complement your music collection, display music charts, and help you find and fix errors in your song meta data, like typos and wrong genres. It also allows you to blog about selected songs or playlists.
