Top Left: A binary black hole shadow viewed side-on. We see two main shadows in the centre, surrounded by a hierarchy of eyebrows, whose eyebrows have eyebrows upon them, ad infinitum. Top Right: Symbolic dynamics to describe photon orbits around two black holes. Bottom: Using symbolic dynamics as a guide to construct one-dimensional slices through a binary black hole shadow.
