The Demonstrations team has been very busy behind the scenes lately. Even though I work on the Wolfram Demonstrations Project every day, it amazes me to see that we’ve published nearly 2,000 Demonstrations already. And we’re working hard to add site features (many of which are user-suggested) at the same time.

Here are some of the features you may have noticed from a major update a few days ago:

View Source from the Web

Under each Demonstration’s animated web preview, you’ll now see a direct link to the notebook file with the complete source code for that Demonstration.

These have always been available from inside the Demonstration notebooks themselves, but now source-code addicts like myself can get their fix without going through a two-step process, which makes it even easier to grab pieces of code and incorporate them into your own work.

Control Suggestions

The interactivity of Demonstrations isn’t limited to dragging sliders and pushing buttons, and now each Demonstration includes appropriate hints about other ways to explore. Download the Demonstration, and you’ll see the hints right under its caption and can mouse over each hint to see a full explanation.

More Powerful Authoring Area

Demonstrations authors were flooding me with requests to include more information in the main authoring area page to better track the progress of each uploaded Demonstration. You can now see the upload and submission dates and delete individual Demonstrations or submit them for publication right from this page.

And of course anyone with Mathematica 6 can author Demonstrations.

Tagging Update

As the Demonstrations site expands in breadth and depth, we are continually updating the classification scheme to allow you to effectively find what you want.

In consultation with our expert reviewers, we’ve completed a major revision to include new topics like control theory, microeconomics and nanotechnology.

The Demonstrations team would also like to send a big thank you to everyone who has participated in the project. It would be impossible to make a site this large without the community of contributors that has grown up around it. Contact us with your ideas and keep the Demonstrations coming!
