Zoom in on a fractal diffusion front in a bidimensional medium obtained by means of a random walk process [Zoom sur un front fractal de diffusion dans un milieu bidimensionnel obtenu grâce à un processus de marche aléatoire].

The bottom line of the bidimensional square lattice is a source of particles (with constant concentration). From time to time, each particle is free to move to one of its four neighbour sites -East, South, West and North- on the condition this site is free (see a zoom in on the first steps of this process: ). After a long simulation time, five subsets can be defined:
