In 2017, A Door In A Wall created a bespoke immersive game for The National Gallery in London. Inspired by the stories of rare paints and pigments, the game used actors, technology, props and hidden clues to encourage the invited audience to explore and interact with the spaces and the gallery's magnificent collection during an evening showcase. The event was curated by the events team at the National Gallery, with catering by Moving Venue, production by Event Concept and flowers by Veevers Carter.
