CAMERAS THAT look round corners already exist. But they rely on specialised lasers which blink on and off trillions of times a second, and light detectors sensitive enough to track individual photons. Something simpler and more robust would be desirable. And, as they describe in Nature, a team at Boston University in Massachusetts, led by Vivek Goyal, think they have the makings of one.
