It's pretty clever, the setup they have that found this thing. It's an *elegant* algorithmic solution to the problem, "how do you measure what angle gamma radiation is arriving from, if you can't* bend, focus, or reflect it; only block it?" https://swift.gsfc.nasa.gov/about_swift/bat_desc.html https://swift.gsfc.nasa.gov/about_swift/bat_desc.html https://en.wikipedia.org/wiki/Coded_aperture https://en.wikipedia.org/wiki/Coded_aperture
