In this picture of a Lakota Indian's winter count, taken from Powell's Writing: Theory and History of the Technology of Civilization, there are too many numbers and logo grams to make clear sense of at first. In addition, the numbers do not follow from right to left, or from left to right, they actually go down a row, then up, and then back the other way and so on. That gets very confusing at first, but if that wasn't enough, sometimes, due to space constraints, numbers are totally out of alignment with where they should be, are drawn so small as that they are almost missed altogether, and hinder quick understanding of this count.
