GoKawiilDeveloper builds interactive 3D simulation of Enigma machine, posts on Hacker News
A hobbyist shared a Show HN post featuring a working 3D model of the WWII-era Enigma encryption machine, demonstrating how a message is typed, encrypted letter by letter, and transmitted via simulated Morse code over radio. The project visualizes how the encrypted signal could be openly broadcast yet remain unreadable without the correct machine settings.
