Here are some photos.
This one is 3 concertinas inter laced. I think it could hang nicely on a wall (which is always a question for books!).
This one is made from an offcut of the one above: each page is about 1cm square
This final one is a plain old concertina, but I am back in love with it for its simplicity. I am still working on an appropriate cover for it.
Again, these were all made from the same piece of paper / 2d art work.
