Have you ever thought about using a teleprompter, like they use on television and some stage shows? You know, the kind where the script scrolls by, so the performer can read his part. I was reading a blog that had one listed on it, as I was reading the website it referred to, and seeing the price. I thought that it sounded like a web page, with auto scroll, so the words would scroll down the page. So a quick Google search of the web and I found a free teleprompter that runs on Windows and I think it does everything the paid one did, plus more. Here's the site:
