The exhibition will show off several garments designed to either stymie or protect against various privacy-probing surveillance technologies, including a shirt with an X-ray-deflecting patch over the heart, an "off pocket" that zeroes out your phone's signal when it's inside, and the aforementioned hoodie and scarf, both engineered to conceal the body's thermal signature that can be picked up by the IR sensors built into many surveillance cameras and drones.
