Patty found some terrific resources that I had never seen before. 

The first is a data representation Applet that demonstrates different interpretations of the same 32-bit number in Java.  You enter a number (in decimal, binary, hex or 4 character String and it shows you how Java stores that value.  I’ve never seen a tool that does a better job demonstrating data storage.

The second is a “sorting lab” that includes a Java Applet that animates different sorts.  I’ve seen a number of these and this one is a terrific non-static animation.  It also has the advantage that the animation does not provide the Java source code for the sort.  Most animation sites show you the source code as the sort is executing, which kind of gives away the solution

There is a lot more on this Web site.  David Eck is a professor at Brandeis.  Resources include:

A free online textbook
Applets and labs used with another free online textbook, called “the most complex machine.”
