The Star Wars credits style is a variant of the Crawl animation. In this style, the text crawls from the bottom to the top, as it also does with Crawl. Additionally, the text diminishes in size all the time until it fades into oblivion. It is a real neat effect, and it is possible to accomplish it in PowerPoint 2010 for Windows if you combine multiple animations.
