Not easily. My line of thinking is that each person puts a dot on a secret map. To populate the map that we see they take the vector between each two dots (positive and negative version of that vector) and put it on the baseline map. So if there is only one person on you will see a single dot in the middle. Two people causes 3 dots. Two dots representing your distance to them and their distance to you plus the dot in the center. 100 people on = 9901 sum of 1-99 * 2 + 1.
