Every object has a skin. Thick or thin, rough or smooth, porous or impermeable, the skin is the line between the hidden inside and the outside we experience. This volume presents products, furniture, fashion, architecture and media that are expanding the limits of what we understand as surface. Reflecting the convergence of natural and artificial life, the work shows how enhanced and simulated skins appear everywhere in our contemporary world. Designers manipulate the relationship between the inside and outside of objects, garments and buildings, creating skins that both reveal and conceal, skins that have depth and complexity as well as their own behaviours and identities. The volume features the work of designers and architects such as Greg Lynn, Petra Blaisse, SPEEDO, Morphosis, Ross Lovegrove, Marcel Wanders, and others. It also contains essays on artificial skin and digital surfaces, and a glossary of surface materials.
