New York artist Nancy Burson used her invention, called the Human Race Machine, to generate the series of composite photographs that appears with this article. The machine takes a photograph of an individual--in this case, a white woman--and adds and subtracts various outward features of racial identity to show what a person might look like if he or she were a member of another race. Burson says she seeks to use her work to underscore the commonality of humanity. And indeed, outward features often say little about the bulk of a person's genetic makeup. The Human Race Machine was one of the most popular attractions at the Millennium Dome in London, where it drew hundreds of thousands of people.
