I've experimented with simple ways to use hypertext to navigate information (most of these appear in my <a href="http://www.cs.cornell.edu/Info/People/karr/lego/index.html">Web site about LEGO toys</a>), and I've been hacking Java applets (executable code that a Netscape 2.0 browser can download and run), for example a <a href="http://www.cs.cornell.edu/Info/People/karr/java/Birthday.html">birthday puzzle calculator</a>. and a tool for <a href= "http://www.cs.cornell.edu/Info/Projects/HORUS/hardening/demo1/HorusStack.html" >verifying properties of Horus protocol stacks</a>. </p>
