The 15th edition of Vivid Sydney, the Australia's largest annual celebration of light, music, and ideas, concluded on Saturday, dazzling millions with its luminous dreamscape. This year's festival, themed "Dream," transformed the city into five immersive zones, with iconic landmarks like the Sydney Opera House and Harbor Bridge illuminated nightly in a symphony of light and sound. From 18:00 to 23:00 each evening, cutting-edge 3D projections, interactive installations, and a giant "Fly to the Moon" installation by a Chinese artist transported visitors into cosmic realms. "The pictures are really great, so we are really really happy," said Chitransh, a tourist from India. Since its 2009 debut, Vivid Sydney has evolved into a global drawcard. Preliminary estimates suggest this year's 23-day event attracted 3.2 million visitors, injecting 180 million Australian dollars (about 117.2 million U.S. dollars) into the local economy. "For Vivid Sydney, I think it will go from strength to strength. It's a fantastic event. We have terrific visitation from China and all over the world and within Australia," said festival director Gill Minervini. The festival's fusion of art, technology, and gastronomy continues to cement Sydney's reputation as a must-visit touristic destination. SHOTLIST: Sydney, Australia - Recent 1.
