As the weather turns grey and days become shorter, it's natural to start feeling a little down and lethargic.\nAs freezing temperatures and darker days force us to retreat inside to a more limited physical environment, it can become difficult to rouse enough motivation to head out and enjoy one of the many wintry activities the city has to offer.\nALSO READ: Trudeau Is So Unbelievably Popular Right Now That It Looks Like He'll Be Prime Minister Of Canada For At Least 5 More Years\nTL;DR Luminothérapie returns for its 9th edition this year in the form of giant, musical dominos. Players can topple, scratch, and kock on the pieces to create music. The installation will operate from December 11, 2018 to January 27, 2019.\nIt is for this reason that nine years ago, officials first introduced Luminothérapie, a now-annual display of light and sound at Montreal's Place des Arts.\nThe point of the interactive display is to encourage movement and social exchange. Playful sounds and soothing colours provide a respite from the harsh reality of winter.\nLuminothérapie takes a different form almost every year. Last year, planners revived the musical, illuminated seesaws that were so popular when they made their debut in 2015.\n@quartierdesspectacles_mtlembedded via\nThis year, we're thrilled to announce that the display will take the form of giant dominos! This latest installation, titled effet domino, is a work of design agency Ingrid Ingrid.\nThe dominos will produce music as you topple them. According to the press release, "every set [of dominos] features a different sound profile (vocals, percussion, marimba, balafon, flute and so on), and when players topple the dominos in a long cascade, the resulting multi-coloured domino orchestra plays a unique musical work in a colorful and luminous bow of pastel hues!"\n"Players can join forces to set up the dominos faster and trigger the next cascade, or nudge them in the opposite direction to reverse the sound sequence. And since each domino makes its own unique sound, visitors can even play DJ by 'scratching' a domino, spinning it at different speeds or drumming on it with their fingers."\nLuminothéapie will operate from December 11, 2018 to January 27, 2019 in the public space right next to the Montreal Musée d'art contemporain (MAC).
