Rebirth of a Nation, Computer Style

How do you go about creating the 49 combinations of progeny from the seven men and seven women featured in the TIME picture chart shown below? Doing so by the scientific rules of genetic engineering -- themselves extremely complex and not yet fully understood -- would be impossible. Instead, TIME chose a software package called Morph 2.0, produced by Gryphon, to run on a Macintosh Quadra 900. The Morph 2.0 is an offspring of Hollywood's sophisticated special-effects equipment used to produce such eye poppers as Michael Jackson's celebrated metamorphosis in his Black or White video and the evil robot that wreaks havoc in Terminator 2.

Morph 2.0 enabled TIME to pinpoint key facial features on the photos of the 14 people of various racial and ethnic backgrounds chosen for the chart. Electronic dots defined head size, skin color, hair color and texture, eyebrows, the contours of the lips, nose and eyes, even laugh lines around the mouth. The eyes in particular required many key points to make them as detailed as possible; otherwise the results would be very erratic. Similarly, miscalculating the dimensions of an upper lip only slightly, for example, could badly skew the resulting face.

Most of the images, or "morphies," on the chart are a straight 50-50 combination of the physical characteristics of their progenitors, though an entirely different image can be created by using, say, 75% of the man's eyes, or 75% of the woman's lips. After the eyes, the most important parental feature is the neck, which often determines the gender of the morph offspring.

Sometimes pure volume counts. The more information extracted from a given feature, the more likely that feature is to dominate the cybernetic offspring. Even when the program is weighted 50-50, if an African man has more hair than a Vietnamese woman, his hair will dominate; the same thing applies to larger lips or a jutting jaw. One of our tentative unions produced a distinctly feminine face -- sitting atop a muscular neck and hairy chest. Back to the mouse on that one.
