This catalogue is published on the occasion of Formafantasma: Cambio (4 March – 17 May 2020) at the Serpentine Galleries. Cambio (from the medieval Latin cambium, ‘change, exchange’) is an ongoing investigation conducted by Formafantasma into the extraction, production and distribution of wood products. For this project, Formafantasma collaborated with experts from the fields of science, conservation, engineering, policymaking and philosophy. They have gathered a range of texts, interviews and visual materials for the publication that pose questions about the role that design can play in translating emerging environmental awareness into informed, collaborative responses. The catalogue includes texts by: Jennifer L. Anderson, Paola Antonelli, Emanuele Coccia, Formafantasma, Lesley Green, Rebecca Lewin, Vanessa Richardson, Paulo Tavares. Additionally, the catalogue includes interviews with: Faustino Londoño & Nelson Ortiz, Frederic Lens, Mark Nesbitt & Caroline Cornish, Philipp Pattberg and Pieter Baas. It is designed by SJG/Joost Grootens and Dimitri Jeannottat. Extending the principals of this project to the catalogue, the paper used in the book has been microscopically investigated to confirm it doesn’t contain cells from endangered species.
