Choreography of the skies shows flight paths
We've all seen Aaron Koblin's Flight Patterns, so we know that there's a certain rhythm to air traffic. GE, who has an aviation branch that designs engines, takes a more local approach to showing air traffic over the course of a day. I'm not sure how to describe it other than multi-stream video, or something like that. Just watch the video below.
Compositing. That's it.
Maybe a better way to describe it would be as a less exciting version of Nike's human chain commercial, featuring Lance Armstrong, Deron Williams, and other famous athletes.
