Believe it or not, you can actually view a QuickTime movie in the Terminal, in ascii form. Get the binary from Apple's Developer Pages:ASCII Movie Player. After downloading, just make sure the file is either in a directory on your path, or run it from the download directory (with a "./" in front), and type ASCIIMoviePlayer some_movie.mov.
Suggestion - use a movie that is not too large, or reduce your terminal font very small. I can watch the Two Towers trailer on my 800x600 screen with 6 pt Courier in the Terminal.
It's all pretty useless, but neat nonetheless.
