“Each of the lines is a path of a stochastic process. They are all

generated by the same rule, but because of the randomness each path

comes out differently in the end and I drew all of them into the

same picture.

The plane is divided into square cells, and the process is constructed

so that it normally just runs in circles inside one cell but, because

of random fluctuations, from time to time is pushed into a

neighbouring cell. (In technical terms: the picture shows solutions

of a stochastic differential equation.)”
