Let's Crack Zodiac - Episode 4 at Cryptologic Museum 🕵️‍♂️

Thank you to the National Cryptologic Museum for inviting me to give a virtual lecture!
https://www.nsa.gov/about/cryptologic-heritage/museum/

This is a general overview of the Zodiac case, emphasizing the many mysterious letters ciphers sent by the Zodiac Killer during his reign of terror in the last 1960s / early 1970s.

I also showcase some of the Zodiac copycats and the ciphers that they created.

At the end is a Q&A session with the audience. Some interesting questions were asked!
