What is Cicada 3301?

On January 5th 2012, an image was uploaded to various image boards. It contained two messages. One was obvious & easy to read. In white letters on a black background it said:
Hello. We are looking for highly intelligent individuals. To find them, we have devised a test. There is a message hidden in this image. Find it, and it will lead you on the road to finding us. We look forward to meeting the few that will make it all the way through. Good luck. 3301
As promised there was another message hidden inside the image. It was the start of a bizarre, as yet unexplained chain of complex hidden messages leading those who could solve them on a journey across the Internet and around the world towards a destination none of them could predict with certainty. Is it a highly evolved ARG? Is it a recruitment campaign for the NSA? Welcome to the mystery of Cicada 3301.
