What is a face? AI will teach us. Maybe. Is there anything like a set of templates, of "building blocks", that any human face is composed of? Is it all about metamor-phoses of an archetypical face?

Dimensionality reduction techniques like PCA (Principal Component Analysis) find structure within data. The application of PCA to facial recognition datasets produces well-known (in the Computer Vision literature) sets of facial archetypes, "eigenfaces".

Who are we??

We randomly combine these archetypes to get variations on the theme of a face. Creepy smiles. Androgynous gazes. Moustaches. The future of humanity?
