On New Year's Eve, over 2,000 drones lit up the Shanghai Sky over the Huangpu River. A perfect way to celebrate especially for a city that has a huge population with big time pollution problems. Or areas with wildfires like Australia, the Amazon Rainforest, and many other places all over the world destroying eco-systems. This cutting edge production w/ drones is an Amazing way to celebrate the ringing in of a New Year! In this case over 2,000 drones, fitted w/ multi-colored lights that were controlled by a central computer, were programmed to fly around and create beautiful images in the sky. Ringing in 2020 like a Boss ... a much Greener Boss!
