There's a larger-than-life salmon migration happening under a bridge in Vancouver. It's called Uninterrupted and it's an ambitious and colossal digital projection from filmmaker Nettie Wild (renowned for her films on compelling issues of the land and its people). This most recent offering from Wild brings the journey of wild salmon to an urban setting in the most vibrant way.

Fish farming is in the spotlight right now. Wild salmon and other species are being considerably threatened with disease and pollution. But Uninterrupted doesn't concentrate on a sense of foreboding though. The show creates a sense of wonder with its huge shimmering projections of salmon and an original score.

The piece was a massive undertaking - the footage was 3D mapped and edited in virtual reality before it was digitally projected underneath the Cambie Bridge. In this video, we see the steps it took to create the installation and what it means to its maker, Nettie Wild.

At its heart, Uninterrupted is an environmental love letter that encourages us to consider our impact on drastically declining salmon stocks and the importance of keeping this ancient migration cycle going.

Uninterrupted is on in Vancouver until September 24.
