THE TREE TOP
The world of songs and noises of all sorts (Francis Hallé)

The summit of the Tree is a 60m diameter dome posed on branches between 170m and 200m
(Le diameter of the Invalides dome is 28m)
(Le diamètre de la coupole des Invalides est de 28 m)

The "tracé régulateur" draws 6 branches of 13 or 10 flowers.

How do we distribute in a harmonious way a fixed number of points on a sphere? Which triangulation should be used? How do we find algorithms which can determine the roots of polynomials? The facets of a golf ball, slugs in the heart of a spherical nuclear reactor, or... holes of a colander ?

	In the summit, 314 fireflies posed on 314 m² illuminate the loop of the river and dialogue with the cosmos. The minimalist lighting of an environmentally freindly project.
