The mini-book samples like this red one from Lucy Frycova came out of a recent class taught by Spain’s Fabi Ajates.

The cover swivels on a screw (I’m guessing) to show the book’s hidden message. Lucy shows several other versions on her FB page. This one is mysterious and multilayered.

Fabi designs the coolest projects that retain their freshness no matter that they’re samples from classes. How does she get her students to do that?
