I love to create demo scenes, and spend a lot of free time for this things, i know standard tools for movies and demo scenes - Flash animation, but i know another methods for animation, first time Power Point 2007 looks like a useless thing, any hard effects or too many objects causes very big speed problems, maybe they and named Power Point 2007 as slide show demonstration

but i show another hidden side of this application, it can run very fast!
