Exhibition Idea Three.

For my last idea I wanted to think outside the box like our tutor's have repeatedly encouraged us to do.

 So I came up with the idea of using invisible ink, a Ultra Violet torch and a normal torch.
For this piece I would write something on paper, very neatly of course. This could possibly be a short explanation of the function if/else. I'd have it mounted somehow within my exhibition space.
In front of this I would place two torches, one containing a normal bulb and one a ultra violet bulb. These two torches will have to look fairly similar in appearance. The interaction with the user is that if they use the ultra violet torch to shine onto the page then the explanation will be visible, and if you use the other torch you will get no reaction except a bright patch on the page.
