Snapping a picture with a camera that doesn't exist is pretty spooky, but doing it in stereo is doubly so. A strange kind of photography known as ghost imaging has been extended to work in three dimensions.
Although the time-consuming technique will not replace your digital camera any time soon, it could make it cheaper to take 3D pictures in wavelengths beyond the visible spectrum, so it could find uses in arenas as diverse as airport security and natural gas prospecting.
