In a recently published TED talk that he gave in August 2013, artist Gabriel Barcia-Colombo presented a special vending machine that he has made—it sells DNA samples that he has collected from his friends.

The photograph on each box lets the buyer know how the owner of that particular DNA strand looks like.

If you are wondering what one can do with a stranger’s DNA, you may be inspired by artist Heather Dewey-Hagborg, who turned DNA she found on discarded gum and cigarette butts into realistic facial sculptures.
