Finding lots more good stuff and have gotten comparison clips for the changes in Episodes I and II. Like I said, I won't bother much with the comparison clips for the other four films, as I'd rather just describe them with pictures and provide the actual videos. While I'd been to a couple of those sites SilverWook had recommended, I'm surprised how I'd missed a few of them as well, and I've found plenty more good stuff. So I'm making progress towards getting this very comprehensive project together :)
