One nice and interesting example of an interactive graphic hypertext that I found on the Internet is titled as Sun Microsystems, Inc. When you click on it, some pictures of Sun Microsystems, Inc show up. And if you are interested, you can further know some more information about this company such as their products and services, company overview, new server line...etc. by just clicking on the relative graphics.
Here are some more home pages of other microcomputer companies:
