The 4096 first digits -base 10- of 'pi' on a Tridimensional Hilbert Curve -iteration 4- [Les 4096 premières décimales -base 10- de 'pi' sur une courbe de Hilbert tridimensionnelle -itération 4-].
Starting from the bottom front right corner of the [0,+1]x[0,+1]x[0,+1] cube, the spheres are
labelled with the 4096 first digits of 'pi' when following a
tridimensional Hilbert curve -iteration 4-. The radius of each sphere is an increasing function of the digits.
