It started with hair. Donning a pair of rubber gloves, Heather Dewey-Hagborg collected hairs from a public bathroom at Penn Station and placed them in plastic baggies for safe keeping. Then, her search expanded to include other types of forensic evidence. As the artist traverses her usual routes through New York City from her home in Brooklyn, down sidewalks onto city buses and subway cars—even into art museums—she gathers fingernails, cigarette butts and wads of discarded chewing gum.
Dewey-Hagborg’s odd habit has a larger purpose. The 30-year-old PhD student, studying electronic arts at Rensselaer Polytechnic Institute in Troy, New York, extracts DNA from each piece of evidence she collects and enters this data into a computer program, which churns out a model of the face of the person who left the hair, fingernail, cigarette or gum behind.
From those facial models, she then produces actual sculptures using a 3D printer. When she shows the series, called “Stranger Visions,” she hangs the life-sized portraits, like life masks, on gallery walls. Oftentimes, beside a portrait, is a Victorian-style wooden box with various compartments holding the original sample, data about it and a photograph of where it was found.Read more: http://blogs.smithsonianmag.com/artscience/2013/05/creepy-or-cool-portraits-derived-from-the-dna-in-hair-and-gum-found-in-public-places/#ixzz2SdYSKW3F
