Harvey has been looking at the effects of such surveillance on culture for some time. Last year he designed a kind of face makeup called CVDazzle to avert face-recognition software.
In the spirit of fooling cameras – and messing with surveillance – Harvey has now come out in a set of hoodies and scarves that block thermal radiation from the infrared scanners drones use. Wearing the fabric would make that part of the body look black to a drone, so the image would appear like disembodied legs. He also designed a pouch for cell phones that shields them from trackers by blocking the radio signals the phone emits. For those airport X-ray machines, he has a shirt with a printed design that blocks the radiation from one’s heart.
