Artist Heather Dewey-Hagborg‘s project, Stranger Visions, is a wonderful mix of science and art.  Dewey-Hagborg turns a poetic attention to the seemingly innocuous artifacts of life: a hair, chewed gum, a cigarette butt.  Beyond sight, though, the DNA remains of each unique person inhabits these “artifacts”.  She picks up these remains up throughout Brooklyn and brings them to a nearby biology lab.  Dewey-Hagborg extracts the DNA from the object, then information from the DNA.  She runs the information through a program she has written herself that is able to determine physical features such as eye color, hair color, gender, nose width, and so on.  That information is then exported to a 3D color printer to create a sculptural portrait of the unwitting donor.
