Organise an Arts and Crafts Festival, making sure that there is lots of Christian content.
Organise a story telling evening (maybe in a pub) again letting the stories have a bias to God, leading to the question, 'What do these stories mean?'
Have a themed meal - an Indian evening, a Chinese evening, an Italian evening, a Brazilian evening etc. (It could just as well be a 'Cornish' evening. Have a speaker to talk about the culture you are sampling - but from a Christian perspective.
