The Maritime Museum ("Musée Maritime") of Douala in Cameroon, open for almost two years, has decided to host an immersive multimedia room La Case des tempêtes, to tell the real story of a Cameroonian fisherman caught in a storm in a river on board his boat. Moviemex3D has created, along with Cameroonian partners Brixia Energy Sarl, the "Hall of 4D Storm" by combining its expertise in the field of museum exhibition with props and multimedia content.
