Some books just take flexing the brain to another level. Like the Codex Silenda. Well, this book won't let you read it unless it is very sure that you are smart enough to unlock it.
It is a laser-cut, hand-crafted wooden book with just 5 pages of puzzles. Designed by the industrial designer Brady Whitney, the book is awe-inspiring. Whitney had collected funds for it 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," says the website.
Read on and we reveal this mysterious invention.
Once in a while, come such things that have you gripped into them, by the sheer complexity of theirs. And, knowing that it is a challenge to crack them, makes them even more wanted by us. You'll feel the same about this one.
"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."
It is all so mysterious!
"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."
You can head over to Kickstarter and put your name on the waiting list.
You'll get it soon to unravel the journey yourself!
Cool, isn't it?
