Since December central Montreal has been feeling a bit more wintry than usual, thanks to an installation depicting the lifecycle of an iceberg, designed by a local creative studio ATOMIC3.

Drawing attention to the effects of global warming, the installation is in four sections, following a journey of an iceberg from its creation in the Arctic waters to melting in the more southern zones. Each stage is created with tunnels formed of metal arches, which in turn are enlivened by different light and sound installations and become smaller and smaller the further 'south' the 'iceberg' reaches.

The distinctive sounds of the installation are triggered by human movement. In the most northerly end sounds of nature are heard, such as water entering the cracks of the iceberg and melting it, while music and sounds become more frequent in the southern end, representing the proximity of human habitat. By the time the installation reaches its most southern end, the arches have become so small that only children can get into the tunnels, creating warmer sounds and colours with their games and the installation becomes almost a barometer for global warming at this stage.

The iceberg installation is also a winner of the 2012 Light Therapy competition, organised by Montreal's Quartier des Spectacles Partnership for interactive light installations that encourage people to embrace winter.

The founders of ATOMIC3, director FĂ©lix Dagenais and lighting designer Louis-Xavier Gagnon-Lebrun, create urban installations with the aim of transforming public space and lighting up people's everyday lives.

The installation will stay open until 4 February.
