A well-designed interactive web page, with succinct text and a succession of playable cartoon simulations, explains Nobel Prize-winner Thomas Schelling’s work on dynamic models of segregation. It uses animated shapes rather than people, and users can introduce different preferences to the characters and see the results.
Wolfram Demonstrations Project
Graphic representations of various concepts in microeconomics (e.g. monopoly, consumer and producer surplus, Edgeworth Box), macroeconomics (e.g. Solow growth model, Keynesian cross, Lorenz Curve and Gini coefficient), game theory (e.g. Nash equilibrium in 3×3 game, binomial tree) and financial theory (e.g. net present value, price-yield curve). Submitted by various authors in Mathematica, with short explanation of underlying theory, and options to manipulate the diagram by changing the different variables. To do this, and view the demonstrations in the browser, requires download of the Mathematica Player browser plug-in which is available for Windows, Linux or Mac. These form part of the Wolfram Demonstrations Project, hosted on the website of independent scientist Stephen Wolfram as a development of his popular Mathematica program.

Open source repository of common macroeconomic models in the R language. Each page describes and spells out the model, provides example code for numerical simulations, and illustrative output and analysis. The approach is spelled out in a “How to simulate economic models” section. The content of the site is in a GitHub repository.
More than twenty interactive workbooks for Microeconomics, Macroeconomics and Econometrics, created using the Wolfram programming language. Each chart illustrates a concept or model, and gives many parameters that the reader can adjust to see the resulting changes. The interactive workbooks can be viewed online or downloaded to the reader’s computer to run in the free Wolfram player. These were created by Angulo while still an undergraduate at Warwick.
This EconWeb: Introduction to macroeconomics samples is part of the EconWeb service that requires a paid subscription, but via this link you can find three sample modules that are freely available. the modules are “Supply and Demand”, “The Output Multiplier” and “Monetarism”. Each module includes lecture notes and a quiz based on US data, with some modules including PowerPoint slides.
