Watch | One hundred dancing drones light up Sydney’s sky

The sky over the iconic Sydney Harbour was lit up with one hundred dancing drones on June 8 as part of Australia's annual Vivid Sydney festival. The drones flew simultaneously through the air to create a variety of multi-coloured shapes in all sorts of sizes. These unmanned aerial vehicles are collectively known as “Drone 100”. All 100 of the illuminated drones were operated by one main controller. The seven-minute performance will take place every evening from June 8-12, subject to weather conditions.
