"For ten years, artist Francis Alÿs has chased tornados in the highlands south of Mexico City, hoping to penetrate, video camera in hand, the peaceful eye of the storm. This book is a loose compilation of the notes, drawings, paintings, press clippings and extracts from writings that the artist gathered during the last season of filming and the editing of Tornado, one of the highlights of the 29th Bienal de São Paulo. With texts by mathematician Ton Marar, art historian Cuauhtémoc Medina and essayist Alfonso Reyes, this book offers a unique insight into the creative process of one of today's most significant contemporary artists." -- publisher's statement.
