Those interested in criminology, forensics or the basics of voyeurism probably have a decent grasp on what a camera obscura is. For everyone else in the audience, allow us to explain. Used since way before your birth, these chambers are designed with an optical device that projects an image of its surroundings on a screen; you just need a room with a hole in one side, which allows a fine amount of light to pass through. If you've ever watched [insert crime drama here], you've probably seen those magical investigators take a blurred shot of a room wall, zoom it in and somehow draw conclusions about the origins of life. Now, MIT's own Antonio Torralba and William Freeman have developed a method that can "transform the entire setting into a pinhole camera." In other words, any room with a window can be repurposed for forensics. On that note, you should probably consider moving your... operations center to a windowless bunker, STAT.
