For seeing the Electronic Wheel Cipher: If you do not see an image of the Wheel Cipher, you will need to download the Java plug-in. Go to www.java.com and follow the link for the downloading the plug-in (in the upper right corner, as of 12/2003). It may take some time to install the plug-in, but there are many Java-based tools, activities, features, and games on the Web, and it's worth the wait! Once the install is finished, refresh your browser and the Wheel Cipher should appear.
