The Pop-Up Concertina is an accordion-folded booklet with pop-ups, covered on both sides with drawings I made using a bunch of .005 micron pens over the course of several months. (…) You can look at it page by page like a book (which never ends, it just turns over and continues in a loop), or you can spread it out and look at it all as one (double-sided) piece. Every way you look at it reveals new connections and interactions – the cut-outs and folds allow the pages and illustrations to change and connect to each other in different configurations.
