The 16.384 first digits -base 10- of 'pi' (141592...) on a Bidimensional Hilbert Curve -iteration 7- [Les 16.384 premières décimales -base 10- de 'pi' (141592...) sur une courbe de Hilbert bidimensionnelle -itération 7-].
Starting from the bottom left corner of the [0,+1]x[0,+1] square, the spheres are
labelled with the 16384 first decimals of 'pi' when following a
bidimensional Hilbert curve -iteration 7-. The radius of each sphere is an increasing function of the decimals.
