Teodosio Sectio Aurea is a Greek artist whose sculptures are nothing much to look at in the light of day. His genius becomes evident only when the his pieces are strategically placed behind a correctly angled light source. His art isn’t the sculpture he assembled, it’s the shadow they cast. His subjects include: elegantly posed women, the Vitruvian man, and masterpieces of Michelangelo, Pablo Picasso, and Leonardo da Vinci.
