Here are some images of paper models like the ones I mention below. Papercraft is very popular in Japan, which provides me with a pretty amazing opportunity for creative research. These photo-based cutout models are like tiny, mass-produced variations on Oliver Herring's photo-based sculptural portraits. I love 'em.
