An Archimedes spiral displaying 100.000 random digits -from 0 to 9- [Une spirale d'Archimède montrant 100.000 chiffres aléatoires -de 0 à 9-].

Starting from the center of the picture, the spheres are numbered (1, 2, 3,...) when following an Archimedes spiral defined as follows:
                    rho  = srqt(N)
                    teta = 2.pi.sqrt(N)
The luminance of the sphere colors is an ascending function of the N-th random digit (from dark blue -0- to white -9-).

See the same spiral with the 100.000 first digits -base 10- of 'pi':
