It wasn't until the true facts and horrors were revealed that people realised what a terrible event it had been. The Great War exhibition is split up into seven 'galleries' - The Causes , Killing Machines , Over the Top , General Rees , Messages , Peace and the Trench Experience . These are accessible from the main menu screen. When you are in a gallery you can go back to the menu screen by clicking on the Learning Curve logo, in the top right hand corner. Each gallery contains a number of 'sources' which are thumbnails of images that open into larger versions with more detail and text.
Every gallery has it's own menu bar at the left side of the screen.
The buttons vary from gallery to gallery. Each gallery has it's own icon. Clicking on this icon returns you to the main page of that gallery. These are interactive tasks that require you to solve problems or answer questions based on the gallery's sources. These provide additional information about a particular source.
