A tridimensional pseudo-random walk defined by means of 'pi': 3.141592... -90.000 digits, -base 10- with 30.000 time steps [Une pseudo-marche aléatoire tridimensionnelle définie à l'aide de 'pi': 3.141592... -90.000 chiffres, -base 10- avec 30.000 pas de temps].

Then 'DX', 'DY' and 'DZ' are renormalized inside [-DR,+DR]
(DR being an arbitrary constant) and used as the successive steps of an "absolute" tridimensional random walk..
