UPDATE (5/31/07): Lucasfilms has yanked the video from YouTube, so try the Tales of the New Republic site for a much better quality, Quicktime version.
I must admit, I'm fairly curious about Tales of the New Republic. Its origin and purpose are shrouded in mystery. Even the people who you would think know something about it, don't. There is a book that came out in 1999 called Tales From the New Republic, but I can't find anything indicating this animated thing is related to it.
