Continuing the collaboration of over 30 years between the New York-based artists Arakawa and Madeline Gins, this book is a unique and predominantly visual exploration into architecture and its centrality to the project of human self-knowledge and self-formation, carrying philosophical argument into the realm of construction. It asks what is the nature of perception? and how does the human being relate to surrounding space? Recording and documenting what it is actually like for a person to stand within a piece of architecture, this is the first systematic study of the role the body and bodily movement play in the forming of the world. Through a series of computer-generated images of great beauty and intricacy, the reader is presented with ways of reworking the man-made world that is architecture. Going further, the book suggests a revolutionary re-invention of the planet and, by extension, the universe.
