text: # Reflector (cellular automaton)
  
  In cellular automata such as Conway's Game of Life, a reflector is a pattern that can interact with a spaceship to change its direction of motion, without damage to the reflector pattern. In Life, many oscillators can reflect the glider; there also exist stable reflectors composed of still life patterns that, when they interact with a glider, reflect the glider and return to their stable state.
