Ironduke - I just tried your idea of black card with holes.
Some of my stars might be a bit big
but it was an interesting thing to do and I think it has real potential. All I did was shine a torch on it, so in this early effort I only have a small patch of stars, visible on the left side. Give me a longer piece of card and some more torches and I'll really have some fun. Dare I try for a moon?
