"The Journey", an interactive filmic narrative that calls for public participation. This piece of work is based on the homonymous short tale authored by Carlos Sena Caires. The story, divided into seven narrative fragments, relates the adventures of Carlos on his first train trip at the age of eight years old. In order to have access to the filmic narrative, visitors/participants should drive a small wooden train on an oval rail track laid on a table. The bigger the displacement of the small train, the longer will be the duration of the filmic fragment.
