"Crystal Lights Chandelier
kinetic light art installation
The Crystal Lights Chandelier is an art installation for the Tsvetnoy Central Market, a new department store in central Moscow.
The 14 meter wide and six meter deep hanging sculpture evokes the impression of a giant crystal chandelier formed by 49 two meter high crystal shaped light elements.
The installation generates everchanging shape variations, movement and light animations within the array of light elements.
In the evening the chandelier starts to glow like a flower of light. At night the art piece falls into hybernation with only very few movements but a very strong pulsating heartbeat of light giving the Tsvetnoy market with its glass facade a unique landmark appeal in Moscows night scenery."
