A river and a puzzle

This is my final version of the 'river of lenses' project. I've had to compromise as I couldn't use the windows as it would have meant tampering with the fabric of the building. However, I am begining to feel this solution will be better -- easier, cheaper and more controllable. It's out of the main thoroughfare (so safer) and the light above will throw some interesting shadows on the wall. I was never too sure the visual interference outside the window would have worked in its favour. All in all, this really is the best place for it in the Reception area. Next pic of this will be it in situ as it is full steam ahead now so it can go into the exhibition on 19 July first. And it's going to have a little puzzle hidden away in the lenses.
