The Exquisite Book: 100 Artists Play a Collaborative Game, available now for purchase at Amazon. Read more about it at Chronicle Books.
Each artist was given the page that precedes theirs to connect their own image to. They needed to extend the horizon line of the last page onto their page. The book has a super unique format! It is ten accordion fold-outs bound into a single hardcover book. The horizon line that starts on the covers follows a path through the entire book through every artists page.
