Takis imagined an aquatic surface, some fifty meters square, on which 49 multicolored luminous lights of varying heights (between 3.50 and 9 meters) appear to be spring-mounted. Perfectly integrated into the perspective of the historic axis, visible from the Esplanade and from Neuilly, these coloured geometric lights flash and sway in a playful and enchanting ballet.

In 1991, the artist installed his Signaux, reproducing his work at the rear of the Grande Arche, this time directly on the slab. Takis thus marks the two entrances to La Défense with luminous masts, his works seeming to serve as landmarks to mark the entrances and exits of this territory.

Greek sculptor Panayotis Vassilakis, known as Takis, was born in Athens in 1925. He now lives and works in Paris. Largely self-taught, he tried his hand at classical portraiture in the late 40s, before moving on to stylized figures and refined human forms.

Inspired by airports, marshalling yards and magnetic fields, fascinated by light and movement, he borrows his basic materials from manufactured objects to create compositions he calls "Tableau vibratif", "Télésculpture", "Télélumière" and "Sculptures lumineuses".

His first Signaux, piano strings vibrating in the wind, were created in 1955.
