Its visual appeal is outstanding to the extent of creating engagement without hands-on interactivity. Every graphic enhances the discussion presented like a well crafted documentary on a cable network. It is well paced permitting the viewer enough time to process information being presented. Text is used on top of video to add emphasis at appropriate points to reinforce key terms. It can be enlarged full-screen, contains closed captioning for the hearing impaired, and can also be played on a television screen. Impressive creation!

None.
