Pretense design pretends to be something that it is not. Pretense design includes all kinds of designed objects: a pair of glasses that looks like a fashion accessory rather than a medical necessity, a hotel in Las Vegas that simulates a Venetian ambience complete with canals and gondolas, boiler plates that look like steel but are vinyl. In this book, Danish designer Per Mollerup defines and describes a ubiquitous design category that until now has not had a name: designed objects with an intentional discrepancy between surface and substance, between appearance and reality. Pretense design, he shows us, is a type of material rhetoric; it is a way for physical objects to speak persuasively, most often to benefit users but sometimes to deceive them.
