Green Space Dark Skies, produced by Walk the Plank, was a project in 2022 for artists, organisations and people across the UK’s four nations to join together in recognising the importance of our relationship to the landscape. Thousands of people carried specially developed low-impact, geo-locating lights - Geolights - into wild landscapes across the UK. Every event was captured on film, with luminous patterns emerging in shots from the air. Green Space Dark Skies came to an end with four epic journeys to the UK's highest mountains presented in a 15-minute film.
