We have more than 275 interactive simulations on our website. Many simulations run natively in your web browser, but most are downloadable simulations that run in the Wolfram Player. Some simulations have an accompanying screencast showing how to use them properly. Please contact us if you identify problems or have any suggestions. Simulations are described in this screencast.
