JCAT, Java-Based Collaborative Active Textbooks is a Java-based implementation of CAT. Cat is a web-based algorithm animation system. This project is well-suited for electronic classrooms since views of a running program can be viewed on numerous machines. There are 2 versions of JCAT. A non-collaborative version which requires Java 1.0, and a collaborative version which requires Java 1.1. You are also given the choice of Solo, Teacher or Student. If you choose the Solo option, you will be shown a non-collaborative animation that will work with and Java-capable browser. The Teacher and Student options, on the other hand, lead to collaborative animations that, for the time being, only work with HotJava.
Brown University has proposed a new model, Mocha, to provide algorithm animations over the world wide web. Mocha is able to make algorithm animation as simple as surfing the web. Fast responsiveness and user friendliness are combined for easiest use. Currently, the Computer Science Department at Brown University is working of the development of new animation services, improvement of the user interface (such as the introduction of sound), support for 3D animations & 3D graph drawing, and the extension of the Mocha model to the more general domain of software demonstrations over the web.
Christopher Morris from the Computer Science and Electrical Engineering Department at the University of Maryland in Baltimore County has compiled a list of numerous links dealing with algorithms. While this page is under construction, he currently has links to Algorithm Animations, Visualizations, etc.
