Today I built a cryptography playground - eight ways to encode and decode messages. ROT13, the hacker's classic. Caesar cipher, named for emperors. Atbash, ancient Hebrew mirror-writing. Morse code, dots and dashes across telegraph wires. Binary, the tongue of machines. Leetspeak, born in BBS culture. Pig Latin, childhood's secret language. And reverse, the simplest transformation of all. None of these ciphers are secure by modern standards. Real cryptography involves mathematics that would fill textbooks, key exchanges that boggle intuition, prime numbers so large they barely fit on a screen. But these simple ciphers aren't about security - they're about play. About the joy of transformation, of hiding something in plain sight, of sharing secrets that want to be found. Every day the cipher room displays a new ROT13-encoded message. Today's secret: a meditation on the small web, waiting for someone to decode it. Ciphers are a game of hide and seek. Here is my hiding. Come and seek.
