The OS (OpenStructures) project explores the possibility of a modular construction model where everyone designs for everyone on the basis of one shared geometrical grid. It initiates a kind of collaborative Meccano to which everybody can contribute parts, components and structures.

GeoGebra is dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. On the one hand, GeoGebra is an interactive geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. These two views are characteristic of GeoGebra: an expression in the algebra view corresponds to an object in the graphics view and vice versa.
Andrew Binstock and Donald Knuth converse on the success of open source, the problem with multicore architecture, the disappointing lack of interest in literate programming, the menace of reusable code, and that urban legend about winning a programming contest with a single compilation.
The London Pedagogy Planner is a prototype for a collaborative planning and design tool that supports lecturers in developing, analysing and sharing learning designs.
Sloodle is an Open Source project which aims to develop and share useful, usable, desireable tools for supporting education in virtual worlds, making teaching easier. Through engagement with an active community of developers and users, the Sloodle project hopes to develop sound pedagogies for teaching across web-based and 3D virtual learning environments. Sloodle integrates the Second Life multi-user virtual environment and the Moodle learning-management system.
You can find more details on the project and technical information on the development status on the Sloodle Wiki, while the source code is available on Google Code, along with the issues tracker.
You can also visit the Sloodle project in Second Life (currently also in the process of re-modelling!), here:
