Wolfram Demonstrations Project

The site won a Parents' Choice Award in 2008.

Wolfram Research's staff organizes and edits the Demonstrations, which may be created by any user of Mathematica, then freely published[1] and freely downloaded.

The Demonstrations run in Mathematica 6 or above and in Wolfram CDF Player, which is a free modified version of Wolfram Mathematica[2] and available for Windows, Linux, and macOS[3] and can operate as a web browser plugin.

The website is organized by topic, for example: science,[5] art, and biology.
