I have this decades-old memory of science magazine articles about acoustic imaging using phased microphone arrays. Unlike phased-array radars of the time, it claimed to be passive and the imagery was shocking. The example images I recall were underwater and looked like some ray-tracing scene but where the surface ripples were like ceiling lights. It seemed like the kind of thing that was going to revolutionize sensing applications. I remember wondering whether it could work in air instead of underwater, such as to provide better visual sensing in fog/smoke conditions. But, I have trouble finding any reference to it, and always wondered where it went...
