Se upp med var du spottar. En 3D-artist vid namn Heather Dewey-Hagborg som bor i New York letar fimpar och tuggummin på gatorna. Hon kan sedan extrahera DNA och med en 3D-printer skapa en hyfsat porträttlik modell av dig.
"We leave genetic traces of ourselves wherever we go -- in a strand of hair left on the subway or in saliva on the side of a glass at a cafe. So you may want to think twice the next time you spit out your gum or drop a cigarette butt in public. New York artist Heather Dewey-Hagborg might pick it up, extract the DNA and create a 3-D face that could look like you. Her project, "Stranger Visions," fashions portrait sculptures from bits of genetic material collected in public places."
