REDLisp is currently only an interpreter of a new dialect of Lisp. It already has GTK and SDL_mixer support. Functions partially work. Macros will be added very soon, as will classes, multiplatform sockets, and threads. REDLisp isn't meant to replace any current Common Lisp implementation, but is just a pet project of a college student.
DrProject is a Web-based software project management portal that integrates a revision history viewer with issue tracking, mailing list management, a wiki, and other features. It is not a learning management system; instead, it is designed to introduce students to the tools that professional development teams use to coordinate their work. Unlike its industrial-strength cousins, SourceForge and CollabNet, DrProject is easy to install and administer. It has a very simple interface: students can learn all of its features in less than an hour. It provides a scripting interface that can be used to automate bulk or repetitive tasks.
Design Center is a Web application that allows users to change the colour of different layers in a photo. In a photo of a bedroom, there could be layers for the walls, the ceiling, and for the floor. The application lets users change the colour of each and see how a new paint job would look. If used on a furniture store's Web site, different layers could be used for beds, chairs, lampshades, etc. to allow customisation by users.
PHPContracts is a design by contract framework for the PHP programming language. It can be used in an object-oriented manner or with simple functions. Design by contract is a style of programming where classes and methods have a "contract" specified for them. If the contract is violated, then there is a defect/bug in the program.
