Visitors to Antoni Gaudi's Sagrada Familia basilica this weekend were treated to a spectacular 15-minute light display on the walls of the iconic church.
The Canada-based Moment Factory, which produced the show, said their ideas were inspired by Gaudi's original colour sketches and notes.
The display, called Ode à la vie or Ode to Life, was part of the Mercè 2012 festival and was a gift to the city of Barcelona from the Canadian city of Montreal.
