Welcome to my channel!  I regularly post videos about the Zodiac ciphers, the mysterious puzzles created long ago by a still unidentified serial killer.  Here you'll find my web series, called "Let's Crack Zodiac".  It started as an exploration of topics surrounding the Zodiac ciphers.  To my surprise, we cracked the famous Zodiac 340 cipher by episode 5:
