Half-term break/Installation ideas

Just before half-term, I have been ill and not been well enough to do any work. I have however been thinking about my installation and the idea I had to make a 'cage'. With the time-scale I have and limited resources, I feel I need to simplify my idea and make something more realistic. 
I have found it difficult to think of an idea, bearing in mind the initial idea I had and meaning behind it, (the feeling of being 'trapped in love' and the cage becomes one place I could put a memory in to) I didn't want to stray from this.

I have been inspired by the exhibition at Howarth Art Gallery and by one piece in particular. I like the idea of using cellophane and light together. Maybe I could make a structure like this one and project my film onto the cellophane, incorporating light (coloured bulbs) and my sound piece?
