JFLAP, JAWAA, jeLLRap -- Visual and Interactive Tools Tools (Java programs) for visualizing and interacting with theoretical computer science concepts. JAWAA is a tool for creating algorithm animations on the web. http://www.cs.duke.edu/~rodger/tools/tools.html

Leonardo An integrated C programming environment for reversible execution and logic-based software visualization developed at the University of Rome "La Sapienza". http://www.dis.uniroma1.it/~demetres/Leonardo/

3 Sorts of Sort CAL Package Several sorting algorithms explained using a nice playing card based interface. http://www.csis.ul.ie/modules/cs4111/3sorts/

Sorting Algorithms Visualizations of some comparison based sorting algorithms. http://www.scs.carleton.ca/~morin/misc/sortalg/

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. http://opsis.sourceforge.net

The Complete Collection of Algorithm Animations An extensive list of links to algorithm animations, primarily Java applets. The list is organized by site and by algorithm. [Not recently maintained.] http://www.cs.hope.edu/~alganim/ccaa/

Hope College Animations Online animations of algorithms and data structures. http://www.cs.hope.edu/~alganim/

LYDIAN Simulation and visualization environment for distributed algorithms that provides students with an experimental environment to test and visualize the behaviour of distributed algorithms. http://www.cs.chalmers.se/~lydian/

Backtracking A combinatorial puzzle is presented making visible the performance of a backtracking algorithm (requires JavaScript). http://www.faust.fr.bw.schule.de/mhb/backtrack/backtren.htm

Java Applets for Data Structures and Algorithms Demonstrate fundamental concepts in Data Structures and Algorithms. http://www.cosc.canterbury.ac.nz/people/mukundan/dsal/appldsal.html

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. http://catai.dia.unisa.it/

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. http://jive.dia.unisa.it/
