Creative ideas for a powerpoint?

My cl has to do a powerpoint showing that we understand the special features, such as movies or motion paths. It doesn't have to be on any certain subject or even contain information. One example of a finished one is my friend's; she had one of the old time countdown things that start before a movie then the screen said: The Demise of the Titanic. Then she had a black and white movie of a ship running into a glaicer with the water rushing by. It was only one slide long, but it showed the effects needed and she got full points. I can do the effects, I just need a good idea to do it on.
