Today we're excited to announce that the Wolfram Demonstrations Project has crossed the 10,000 Demonstrations mark and is now supporting the latest versions of the Wolfram Language and CDF Player. Launched in 2007, the Demonstrations Project is the largest open web repository of peer-reviewed interactive knowledge apps. With examples ranging from elementary math to medical image processing, the site fulfills a need for professionally vetted, sophisticated, and easy-to-use resources for students, educators, publishers, and anyone looking to communicate technical concepts with graphic clarity.
