[Georgia and the Army]

For those of you who do/have done GCSE art, you'll know what I'm on about (maybe), but for those who haven't/don't, I have to think of an idea for a project for my GCSE art that is loosely based around 'inside and outside'. I've brainstormed a lot of ideas but none of them I really want to do - I want something simple that's there in everyday life but is also really unusual and has never really been thought of to focus on before... anyone have any ideas?
