First, that this is revealed as a real code, a complex one, one that defied the efforts of the FBI and others to decode it for 50 years. I think it te…
Now that we have the full key it’s interesting to look at the distributions of the symbols of the code. We now Z used hard symbols for letters with l…
If anyone could show a source for the "friction tape letter" OTHER than Graysmith, that would be great. All we know is what he wrote in a bo…
Being a historian means being a scientist and thus using the scientific method, among others: Ockham’s Razor – that’s why I don’t think, for example, …
Just a minor observation. The "one down, two over" pattern could be thought of as a variation on a "knight’s tour". Chess was re…

For years many assumed the cipher was improperly coded or deliberately unsolvable. The fact it took 51 years to solve what is an ingeniously encrypted…
To my untrained eye, this seems like a complex code. Does this indicate Zodiac was much more proficient at code making than the 408 seemed to indicate…

Wow. You guys actually did it. Absolutely amazing! Congratulations! It’s kind of incredible to see how a lot of little intuitions built up over time …
Hi I’m new here. Not sure where to post this on this site, but here’s my take on the 340. Please see: Trying to understand your key, which you didn…
Great video! What did you use for the animations? They are awesome! Some of them are done directly in the video editing software (Final Cut), but I ha…
Really nice job. Very cool graphics and animations!
One of the things I like about this idea is that it would give the author enough flexibility to hide little easter eggs and false leads in the cipher,…
