Winter Break Of Code Day Thirteen
My ten-year-old mind was completely blown when I realized that I could eavesdrop on the walkie-talkie conversations of the other kids in my neighborhood. I rode my bike to the library in stunned silence, found a book about codes and puzzles, and raced home to my computer. I reluctantly transformed QBasic into something other than a conduit for modified games of NIBBLES.BAS and GORILLA.BAS, and wrote a Caesar cipher implementation that worked in both directions. That ended up being the easy part.
