Before jumping straight onto a computer, I thought it might be helpful to draw out some potential ideas so that I don't forget whilst focusing on one idea. These can be seen below. I particularly like the designs 1, 2, 3, 13, 5 and 7. So these are the ideas I am going to take forward and develop further. These are quite vague to someone who doesn't understand, however I have the initial idea on paper and I will explain each one once designed properly.
