New Theory based off the added phrase to the instructions page yesterday: [quote]Think not of locations, but the spacings between, as seen from each target. While one hemisphere provides a strong center, the other must heed the call in order to bring light to the unknown[/quote] Imagine for a second that each person adds a dot to a real world map back on Bungie's servers - not the dotted image on the right side of each day's puzzle. Now imagine that each pair of dots on the hidden map give a magnitude. Two people in the center of the US would have a small magnitude (Line A - B). But if someone logged in from Australia (C)there would now be 3 magnitudes {A-B, A-C, B - C}. One small magnitude from A-B, and two very large magnitudes A-C and B-C. This could populate the dotted visible image with 3 dots. One dot near the center and two dots near the edge of the image (given some rotation possibly based on time of day). Now imagine you have a cluster of people within the US. All you need is 1 person to log on from Australia and then you instantly get a cluster of points near the outer region of the image because you automatically gain the magnitudes from that one person to the entire cluster of people within the US. So like the instructions say it's not about the location. It's about the spaces between the location that allow us to see different areas. The hemisphere part is only slightly relevant just because you can't get any further apart from another single person than half the world. So it may not just be we need people in the southern hemisphere. Another possible method for getting rotation would be that you actually use the direction from person 1 to person 2 and use that vector to populate a dot. (You automatically get the positive and negative vector which makes since since the FFT is mirrored that way anyways) I don't know if this changes anything but I would be interested in setting up some experiments on the earlier day's puzzles to test out this theory if someone is interested.
