Perhaps one not just for the aviation geeks - air traffic controllers have come up with a fancy way of representing flight patterns in some of the busiest airspace in the world.
The UK's NATS (National Air Traffic Services) organisation has placed each of the thousands of flights which make their way across the Atlantic from Canada and the US to the UK, Ireland and mainland Europe.

Here is the European data map:
