Marion Bataille’s ABC3D is a book of the alphabet -- done pop-up style in red, white, and black ... and one mirror.
The design is clever, though he uses only about 12 concepts and repeats several of them across different letters. But what is extraordinary is how he surprises the reader with similarities among letters (E/F, sure; but wait until you get to O/P/Q/R!) -- and within letters (there's a mini-me in G!). He makes me want to learn about typography and alphabet history.
Watch a video of the book (audio alert) below. Note: It shows the entire book (in a little over a minute) but, in my opinion, doesn't "spoil" it. I watched the video and immediately put the book on hold at my library. And I still may get my own copy!
