This website features a detail of a Chuck Close portrait. You may not have noticed at first sight that the banner is part of a face. In this kind of woodcut portraits you only see the three-dimensional shape that is represented at some distance. From too close (no play of words there) the details become inconsistent with the assumptions that the visual system makes about what should be a shadow, according to the interpretation given by Patrick Cavanagh and John M. Kennedy in Science.
