I would have thought the dancing Yoda thing was something someone did either on a weekend or during their lunch break. Not something that took a month (or more) to complete. I cannot imagine putting that much effort into 3 mins worth of footage just to show off a dance class (since it wasn't originally going on the DVD).
How about instead of showing us the dancing Yoda, show us the process that a 3 minute scene goes through in it's creation? I haven't watched all the extras on the ROTS DVD, so maybe they did include something like that. I know the Ice Age DVDs have a behind the scenes look where you can change the camera angle and see the scene at each step of the process.
