Vespers is a collection of masks exploring what it means to design (with) life. From the relic of the death mask to a contemporary living device, the collection embarks on a journey that begins with an ancient typology and culminates with a novel technology for the design and digital fabrication of adaptive and responsive interfaces. The project points towards an imminent future where wearable interfaces and building skins are customized not only to fit a particular shape, but also a specific material, chemical and even genetic make-up, tailoring the wearable to both the body and the environment which it inhabits. Imagine, for example, a wearable interface designed to guide ad-hoc antibiotic formation customized to fit the genetic makeup of its user; or, consider smart packaging or surface coatings devices that can detect contamination; finally, consider environmentally responsive architectural skins that can respond to, and adapt—in real time—to environmental cues.
