Star Wars side-by-side

With the release of the original theatrical versions of the original Star Wars trilogy (yes, Han shot first) coming on September 12th, the folks at StarWars.com have set up slide shows of more than 150 images per movie showing the changes made from the original to the special editions. The comparisons of A New Hope, The Empire Strikes Back are online but the Return of the Jedi comparison doesn't seem to be available yet.
