The Oceanic Preservation Society (OPS) is inviting you to witness a glimpse of its new high-tech projection system this weekend, lighting up the United Nations building in New York City with images of endangered species and climate change. The event is being held ahead of Sunday's People's Climate March, which is expected to draw thousands downtown as world leaders gather for a climate meeting. 

The group's U.N. moment will likely be included in their upcoming film, "Racing Extinction" (previously titled "6") — Academy Award-winning director Louie Psihoyos ("The Cove") said last year that the intention was always to finish there. "It’s a global story," he told Ecorazzi. "We travel all over the world, but we end up in New York for a very good reason. If we do our job right, you’ll know when we’re there and why."

"Racing Extinction," which previewed as "incomplete" at this year's Tribeca Film Festival, follows a team of activists utilizing state-of-the-art equipment to present incredible images that will "change the way we understand issues of endangered species and mass extinction." Director Psihoyos says his vision for the film was influenced by advice that another famous director gave him. 

"James Cameron told me to change behavior you can’t just educate — you need to change hearts and that’s what we try to do," he said. "We have an epic love story and the ultimate subject and we tell this story by showing people something they haven’t seen before in a way that hopefully changes their hearts forever. Our story unfolds like a mystery but quickly escalates into thriller mode. The exposition is delivered while you’re watching the thriller unfold, so it doesn’t feel like a doc, it feel like, well like nothing you’ve seen before. I don’t know what the genre is but if we succeed it will be sitting on a shelf by itself."

Look for OPS's "illUmiNations: Protecting the Planet" to start projecting on the UN Headquarters on Sept. 20  from 8 p.m. to 11 p.m
