ClassTools.net. The latest addition is a template called Movie Text. Movie Text lets you create Star Wars-like scrolling introductions.
To use Movie Text simply go to the template found here then click the edit button in the lower, left corner of the screen. Change the text in the template editor to read whatever you want it to display then save it. Once you have saved a template it will be assigned its own URL and you will have an opportunity to grab an embed code to post in your blog.
