Ductus is a wiki system designed to handle arbitrarily-structured content and a variety of workflows. With Ductus, programmers can easily define classes of structured content, providing rich mechanisms for user interaction. For instance, the Wikiotics project uses Ductus to allow people to collaborate on "language lessons," which can later be used as quizzes or flashcards. Such modes of interaction are not possible with most wikis, which are designed primarily to handle freely-structured text.

Dynamic Form is a Python request abstraction library that lets you write one request handler that will run on multiple Python Web frameworks (such as Django and Google's AppEngine). This allows you to create pages and apps once and use them on multiple projects without concern about which framework is being used. Additionally, it makes AJAX easy. Simply adding nested request classes allows you to define AJAX handlers that can easily be refreshed both sever-side and client-side.

Eco-Memory is the classic memory game where the goal is to find matching pairs of cards. The cards represent habitats, organisms, and cultural entities of ecosystems like the Boreal Forest, Coral Reef, Deciduous Forest, Desert, Ice, Intertidal Zone, Rainforest, Surface Zone, Tundra, and Wetland. The game includes a small synopsis of the organisms, the cultural entities, and the habitats themselves. The synopsis is available through an "About" button that you may click after finding a matching pair of cards.
