Couldn't they manufacture them to blink at a time based on the bottom bits of their latitude/longitude? So that lights on the same building would blink nearly simultaneously, but lights on different buildings would blink at discernibly different times?
@weaselx86 Thank goodness buildings are built on a grid 131072 to the degree! 🙃
But seriously, they are already made with customizable blink timing patterns, but the fact that you see entire cities blinking like one giant Christmas tree tells you how much this feature is being used.
