Today's Internet provides a large number of freely available interactive materials for mathematics learning and teaching. Most of these mathlets are ready to use but not ready to be modified or extended. In this article we present a collaborative environment of open source tools around the dynamic mathematics software GeoGebra that gives educators the freedom to create new and modify existing materials in an online community. We describe how to do this based on design principles for multimedia learning and experiences from our work with teachers.
