The 1024 first digits -base 10- of 'pi' on a Bidimensional Hilbert Curve -iteration 5- [Les 1024 premières décimales -base 10- de 'pi' sur une courbe de Hilbert bidimensionnelle -itération 5-].
Starting from the bottom left corner of the [0,+1]x[0,+1] square, the spheres are
labelled with the 1024 first digits of 'pi' when following a
bidimensional Hilbert curve -iteration 5-. The radius of each sphere is an increasing function of the digits.
