Hey this is off topic (posted in another thread as well.) but those looking for more of the CGI Yoda proof in EP1 look no further than here starting at 2:17 http://www.youtube.com/watch?v=NF8yjbNzyi8&feature=related This is even more than the ROTS DVD showed on it's short documentary of the EP 1 CGI Yoda.
This is from STAR WARS IN CONCERT.
