The art of video projection is becoming a widespread phenomenon. “3D projection mapping creates the illusion of multidimensional movement across or around the contours of any surface.” Many cities are now incorporating this ambitious technological art form as part of their events to tell a story using graphic, historic, cultural or mythical content. We have seen fascinating 3D projections on building façades and cathedrals all over the world, from the Sydney Opera House in the southern hemisphere, to the Canadian Parliament Building in Ottawa, to the Sagrada Cathedral in Barcelona.
