Wolfram Demonstrations Project
http://demonstrations.wolfram.com/

Conceived by Mathematica creator and scientist Stephen Wolfram as a way to bring computational exploration to the widest possible audience, The Wolfram Demonstrations Project is an open-code resource that uses dynamic computation to illuminate concepts in science, technology, mathematics, art, finance, and a remarkable range of other fields. Its daily-growing collection of interactive illustrations is created by Mathematica users from around the world, who participate by contributing innovative Demonstrations. Interactive computational resources have typically been scattered across the web–requiring specialized programming knowledge that’s made them difficult and expensive to develop. As a result, their coverage has long been limited, and progress has been slow. In many ways, The Wolfram Demonstrations Project introduces a new paradigm for exploring ideas. The power to easily create interactive visualizations, once in the domain of computing experts alone, is now in the hands of every Mathematica user.
