Most presentations of night lights data I've seen are static, and in time you get a really interesting dimension. See the pop-on of lights in South Dakota when shale oil is extracted starting in 2010. Notice the steady growth of lights across China (easiest to see that China goes dark when the gif loop restarts in the '90's). You get similar steady brightening around Brazil, Chile, and South Africa. Also check out the things that remain constant: the Nile and Indus are the cradles of bright lights, and North Korea is as always a valley of black sandwiched between China and South Korea.
