St Pauls Church in Auckland, NZ have a great history of releasing innovative videos to celebrate the birth of Jesus. This example is actually from a year or two ago but would be terrific to show at a crib or children's service this Christmas.
Heck, show it for a regular Christmas service no matter what the age of the congregation!
If you don't have access to a data projector, put the call out in your parish for whoever has the biggest telly and wheel it up the front of the church, with your laptop connected. Too easy!
If you'd like any technical advice about using videos in church like this feel free to contact me...
