My initial idea

My initial idea (in one of my previous posts) was just an idea I had while reading over the brief. I have since gone off doing something quite so literal and abstracting my idea a bit more to something which people can relate to plus I need to have a metaphor. Because computing and the terms can be quite difficult to learn when you have them in front of you to play around with it's going to be even harder to teach to someone who doesn't have any previous knowledge and the opportunity to test it out and play around with it. Because of this I am trying to relate my metaphor and installation to something that most people can relate to and have experienced or seen.
