Cinderella project can do geometry on the computer, and it is designed to be both mathematically robust and easy to use.
The new release Cinderella.2 is a major step forward and has many new features and enhancements, for example physics simulations and a built-in scripting language.
You can run Cinderella on Windows, MacOS, Linux, and many other Unix variants, because it is written in Java. And since Java is built into many browsers, such as Firefox, Internet Explorer, and Safari, you and others can use your constructions across the Internet. Communicating geometry is easy with Cinderella.
