My brother's going to be visiting this weekend, and he's got some video editing software that can do green screen. We had a phone conversation about trying to think up stuff to do with that when he makes extended holiday visits at the end of the year, but we need some ideas that can done with relatively little preparation.
One thing I contemplated for the Decemberween holiday involves tracking down and buying a very muppety-looking Jesus puppet I once saw online. I see nigh-infinite potential for blasphemous humor, possibly involving a point. I'm a bit camera shy, so I'd let normally inanimate objects do some stuff for me.
So, help us out with a little brainstorming.
