A light sculpture in levitation. When one makes it rotate, it swirls in the air almost forever until air friction eventually stops it.
"At nightfall, lights turn" — the english name of this installation, is composed of articulated arms topped with LEDs. Their common ground is magnetic, and levitates in the air a few centimeters below a supraconductor cooled down with liquid nitrogen.
The whole thing swirls within a cool vaporous cloud of nitrogen steam, diffracting LEDs' lighting. With speed, LEDs become strings of light...

This project was part of a major exhibition organised by the CNRS in Paris, and held both at the Cité des Sciences and the Espace Pierre-Gilles de Gennes.
Designer François Azambourg was commissioned to lead the various design projects presented there.

First attempts by Charlie Zehnlé to make a light levitate and spin at the same time, by the mean of supraconductivity's unique properties.
