Hey Brian525,
The change is called the ClipShift which was created by Chad Nelson. It actually has been talked about numerous times on the forums so next time try and search for it using the search bar right beside "Forums Home".
The DVD entitled Surfaced, which teaches the Clipshift including other effects will be released sometimes next week (people are assuming) on Dananddave.com.
If you need to know any more information on it I recommend contacting Dan or Dave Buck, or Jordan Lapping, who was the one performing it in the Blackpool video.
