Aspiring scientists from the Zurich School of Applied Sciences have built a video simulation that displays the flight path of every commercial flight in the world over a 24-hour period. There isn't much of an application for it, but it sure is cool to look at.

While the map may look complex, Dr. Karl Rege tells us he and his team found it surprisingly simple to assemble using data readily available on the internet. 

"We used a commercial website called FlightStats to gather global flight and schedule information," he says. "So there was no need to contact the different airlines."

Below: Twenty four hours of air traffic above the United States. Notice that around :10 the sky is dark except for red-eyes from the west coast, and then at :15 the east coast explodes with morning flights.

Below: This one shows traffic into and out of Atlanta. Keep in mind that Delta operates the world's largest hub here.
