Crucial Perimeter-1 by Islam AlyIn this book Crucial Perimeter 1, I explore the dichotomy between what's inside a book and what's outside. The book has no text or images on its folios. When the book is closed, the viewer can see the content on three edges of the book, but depending on how the book is opened some of the content on the edges diffuses and becomes illegible, converting into traces of texture.
