I like the idea of medieval stocks, but can't see how a klicky could fit in them, given that their hands and heads wouldn't be able to be in them at the same time
He would have to have his hands in stocks and maybe his head peeping over the top... gah!
As for gallows - I think there was a diorama produced recently (can't find the link) where they had one in the town centre using existing playmo parts.. if I manage to rediscover it, I'll post
