I was just wondering how many different versions of the THX sounder logo that plays before the movie exist. In my collection I have a generic one on a number of titles, Toy Story has the one where the little guy works on the logo and flies through my living room, T2: SE has a killer one on it that melts into the logo and The Phantom Menace is suppose to have a new one as well. I heard a long time ago that they even made a Simpsons one but I don't know if that's true. Any info?
