It is called "PI walk"; a visual representation of pi created by John Venn in his book -- The Logic of Chance, 1888. Each step in the walk corresponds to the next digit of Pi. The number 0-9 is represented by the direction of the movement but the same distance;

Pi as approximately 3.14 or 22/7 but now we all know that it is an irrational number, a number continues forever without any repeating pattern.

" We should also say that the longer we continued to produce such a line the more pronounced would these tendencies become. -- John Venn, The Logic of Chance, p.126 "

One related question is that does it has a secret pattern in the walk? or do all sequences of possible digits is equally likely to appear here? It looks random but technically we still donâ€™t sure that whether it is really random or not. It still be a mathematical mystery.
