One of Barcelona's most famous buildings turns 100-years-old this month. To celebrate, several artists came together to create illuminated pieces to grace La Pedrera's facade. Like much of the city, the art mixes the absurd with the delightful. The show, called "La Pedrera, emocions en moviment" (La Pedrera, emotions in movement) aired Dec. 1.
