from the text: „The laser-cut, hand-crafted, five-page wooden book is created by industrial designer Brady Whitney, who’s been raising funds for the project through Kickstarter. “Each page features a unique puzzle that requires the user/reader to unlock the corresponding bolts in order to progress to the next page,” read’s the website. “As the puzzler moves through the book, a story begins to unfold, depicting the story of an apprentice in Da Vinci’s Workshop who encounters the same Codex. However in the story the Codex acts as a trap set by Da Vinci to capture any would be spies/snoopy apprentices in order to protect his work. The only way to escape is to solve each of the puzzles before the master returns from his trip.” puzzle-book-unlock-pages-codex-silenda-brady-whitney-9 puzzle-book-unlock-pages-codex-silenda-brady-whitney-10 puzzle-book-unlock-pages-codex-silenda-brady-whitney-11a
