The first class I started here at PBI was titled "This is a book (but maybe not a Codex)" and the instructor was Bill Drendle. The objective of the class was to use book forms and content differently than might be expected, disregarding restrictions of a traditional codex.
He presented us with found books and comic books, stamps, found papers and objects of all kinds in an attempt to inspire us. We made rebus books using pictures and text, as well as books containing lists and found dialog. In the end, I made five "books".
This concertina structure was made to accommodate a list, and I had decided to go with a list of alternative subcultures so the materials and imagery were thus influenced.

Another very simple structure he showed us, is this round book made with circles. In my example here, all the circles bear the same image and it sits on a base so you can spin it.
