As the brain attempts to organize the visual world, it hones in on familiar patterns -- like the shape of a human face -- and sometimes, it even concocts these patterns out of random noise. We spot faces in all sorts of inanimate objects, from grilled cheese to buildings to coffee makers. Some objects are even designed with the human face in mind, at times to a creepy degree, as artist Robby Kraft found. Kraft used face-detection tech from Kyle McDonald (on GitHub) to overlay about 67 images of human faces found in the #selfie tag on Instagram; these created an "average" human face after about 15 images (above, left). He ran about 125 inanimate objects tagged #FacesInThings through the same software and, again after just 15 images, an eerily "average" human face emerged from the compilation (above, right).
