Qué grande! Nunca lo había pensado. Me ha encantado.<br />
Por si a alguien le interesa hacerla en Matlab (yo es que el Mathematica no lo uso habitualmente), este es el código. He añadido instrucciones para que salga el fondo negro y las líneas en amarillo (así se aproxima más a la realidad). Pintar el interior de la elipse de amarillo ya es más difícil, ya que la función del murciélago se va pintando por partes.<br />
