That's INSANE!!! I can't even imagine what a big job was done to create such a drone show. Now I realize how talented our people... American cultural development is abandoned now because of lots more ground-up problems in society. But I'm happy to see that we still creating such amazing art objects as I can call this way. I did a lot of papers on this theme and found
here much useful info. And what I realized at the end of researching is the point that we can develop the culture without knowing its past. So maybe someone has ever done a similar show but using something simpler than drones...
