It occurred to me that the Zodiac Killer Cipher Generator was in need of some documentation. While the different inputs and fields are nearly self-explanatory for those of us who are familiar with the Zodiac's homophonic substitution ciphers, there are likely many other people who are less acquainted with the subject, yet are still interested and hence would benefit from some sort of documentation.
Instead of writing down everything I had to say about the generator, I decided it would be easier and more effective to create a simple screencast since this type of information is often communicated most easily through example. The video is not the most polished production, but I am able to run through nearly all aspects of using the cipher generator. Have a look.
