Thanks for the idea !
I have a really grotty assignment to do on Monday I've been putting off all this week. 

Unfortunately I can't find any pictures on Flickr that are suitable 

I'm gonna have to take my own    

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.
