These are Mathematica interactive demonstrations (CDF) I wrote over the last few years. Clicking on the image plays a small movie to illustrate the CDF. Clicking on the link opens a web page that have the CDF ﬁle and source code. To play the CDF, download the CDF ﬁle to your computer and double click on it to run it using the free Wolfram CDF player
