A bidimensional pseudo-random walk defined by means of the Champernowne number -using all base 10 integer numbers-: 0.1 2 3 4 5 6 7 8 9 10 11 12 13... -1.166.670 digits, base 10- [Une pseudo-marche aléatoire bidimensionnelle définie à l'aide du nombre de Champernowne -utilisant tous les nombres entiers en base 10-: 0.1 2 3 4 5 6 7 8 9 10 11 12 13... -1.166.670, base 10-].
RHO = constant THETA = 2.pi.N/10'THETA' being an absolute angle. At last, the square root of the distance from each point to the origin is taken.
