Important Note: After Oracle took over the Java system, the language is not well supported and not promoted as a main tool for active contents in browsers. E.g., neither Android nor IOS can run desktop apps written in Java. Recently, Chrome gave up the support for Java. It is still possible to run Java in some other browsers. If you have such a browser you can experience the beauty of C.a.R. on the pages below. Otherwise, you can download C.a.R. and see the examples locally.
These pages contain demos of the dynamical geometry program C.a.R.
The demo pages are sorted by program features. If you are looking for specific topics in geometry, have a look at the application pages.
Browse through the various feature demos! Don't forget to run the automatic demo!
