Wow this is awesome. Code was an eye-opening book for me as a child. I have a 2 year old, and have been wondering whether he could possibly appreciate camera film ISO codes (an early example of "a code" in the book), given that he'll likely never see a roll of film, or other things like that. An updated edition is great news.
