The Making of a Cool Tracking Shot

I have a particular fondness for tracking shots (long sequences on film with a moving camera that are created in one shot without cuts).  The opening scene in Orson Welle's Touch of Evil is perhaps the most famous, but there are many other examples such as in Goodfellas and in the opening credit roll of Serenity (though what looks like one long shot is actually two in that case).

This making of video for a different sort of tracking shot is really amazing, as it juxtaposes what we see on the film with an overhead view that shows how it is being made.  Total crazyness:
