The document presents three concepts for an art installation to be displayed in the National Maritime Museum's foyer. Concept 1 involves an installation that only forms a certain image when viewed from a specific position, taking inspiration from optical illusions. Concept 2 uses different layers of opaque and translucent materials to create an image that can be viewed in many ways and with hidden details. Concept 3 takes a more interactive approach involving movable flaps or parts that reveal windows and other naval architecture elements, with touch screens behind each flap playing short videos about the history of the place. The concepts aim to appeal to the museum's diverse tourist audience in a compelling yet small installation.
