Tons of great stuff came out of the Arts and Passion-Driven Learning institute - questions and ideas about creativity, inspiration, curiosity, and community and ... ACCORDION BOOKS! In the very first session, we all made our own accordion books.
The idea is that accordion books, being handmade by the people who will use them and, more importantly, being flexible, expansive objects, can engender more creative, authentic note-taking and thinking than a traditional notebook. Since the pages aren't cut, ideas/notes/drawings can run from one panel to the next. Since the physical structure is flexible, you modify your accordion book as you see fit - I saw people attach panels that fold out in different directions, make pockets for little scraps of paper or business cards, and add more accordion pages so the book goes on for-ev-er.
Maybe it was just the spirit of experimentation, but I noticed that I was reflecting and taking notes differently than my usual linear or bullet point/t-chart/Cornell note style. I was also so into my accordion book that, when the conference was over, I spent another half hour at the craft table adding to my book and chatting up people doing the same.
