I think you could be right with the lighting Tom. No doubt it will take a bit of experimentation to get it how you want it, I would love to hear how it turns out and what you decide upon.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
