| Backtracking | | A combinatorial puzzle is presented making visible the performance of a backtracking algorithm (requires JavaScript). |
| CATAI | | A distributed algorithm animation system. Algorithms are coded in C++ and the resulting animations displayed using lightweighted java application. Multi user and interactive animations are supported through the use of a distributed CORBA based architecture. |
| Java Interactive Software Visualization Environment | | JIVE is an object-oriented general-purpose animation system for the visualization of Java coded algorithms. Visualizations can be embedded in a Java browser or attended in a Virtual Classroom by several users at once. |
| Leonardo | | An integrated C programming environment for reversible execution and logic-based software visualization developed at the University of Rome "La Sapienza". |
| LYDIAN | | Simulation and visualization environment for distributed algorithms that provides students with an experimental environment to test and visualize the behaviour of distributed algorithms. |
| Opsis | | A Java applet designed to teach binary search tree algorithms. It is unique in the way it combines programming, proof, and animation to enhance the learning experience. |
| Sort Algorithms Visualizer | | Applet and web site for teaching sort algorithms. Includes animation of 11 algorithms and some in-depth studies. |
| Zeus | | An algorithm animation system developed at Digital Equipment Corporation's Systems Research Center. | |
