A narrator willing to face persecutions and fires, willing to plunge into the depths of the sea or look among the stars, and all this because he has to deliver a coded message. Will he make it? And more important, will the recipient understand his message? Nicolai Troshinsky shows in this books a great many codes with a retro style and the (hard) mission to reach the heart that lies in the other side. Any graphic element that appears in the book, be it words or images, is made out of the symbols and letter available in the first computers. Based on this auto-imposed limitation, the author creates a book that has a distinctive style and a concept that allows him to introduce a complete catalogue of languages, codes and alphabets, like the flag code, the morse alphabet or the NATO phonetic alphabet. A book to play with, experiments and think about. A book that introduces itself as a mysterious object, a floppy disk, arrived from a past that, even if it\'s still recent, reminds us of older ages, a past that disappeared surrounded by a cloud of progress.
