Without more information or a link, I dont think anybody is going to know what you are talking about.
Carefully examine the intro a frame at a time and try and find out what is being done to what. Think in layers. If you are still completely lost then post a link to the effect you want to emulate. Nobody has time to look through the 13,700 hits a Google search turns up for xderturk and try and figure out which intro you want to copy.
What the others said. Provide an exact link and tell us, what specific effect you mean.
