This is linked content that works like internet hyperlinks. It uses the carefully chosen media as memory aids and prompts instead. The clips of sound - Elvis tracks for example - photos of local areas, or film clips - from Casablanca and other films - all date from between the 1930s and 1960s. The aim was to make something that was very accessible to people with no computer skills, and something that looked inviting and easy to use.
