Thanks for all the suggestions – apes and monkeys feaatured very heavily so next one will be a big King Kong climbing up Aylesbury clock tower (Aylesbury being where I’m from). Simon Bensley, also from Aylesbury, was saying he might get a tattoo of the same thing.

Anyway, should be able to get some lines on the wall over weekend – while you’re waiting here’s a photo of the tower in question. It’s the nearest thing we have to a landmark in mid-Bucks.
