Artist Heather Dewey-Hagborg has been taking scraps of DNA left behind from strangers to 3D print an approximation of their faces.

She's used cigarette butts to wads of gum to hair she's found on the street. By using DNA from samples, and a software she wrote herself and a 3D printer, she's been able to theoretically create the face it belongs to.

But don't worry, it's not the faces of those people, but rather a possible face based on gender, eye color, and maternal ethnicity. Dewey-Hagborg tells Co.Exist "there's a whole lot more subjectivity than we're kind of lead to believe."
