Pop-up book needs a lot of mechanism to hide the content while the book is closed, and the 3D part must be able to stand when the book is opened.
JK Brickworks has solved the issue and here come their various version of Pop-up books, and one of these projects are sending to Lego Ideas! Let’s hope they can gain the 10,000 supports!
Anyway, just a personal comment to further enhance the project is that 1 Page is definitely not enough for a book. What says you?
