Can You Face It?
The University of St. Andrews, in Scotland, has developed some face-transforming software that allows people to change the age, sex, or ethnicity of the person in an image that you export from your computer. Or, blend features from a number of faces into one amalgam. If all that is too creepy, then just import art […]
