The famous trick they do which I know that they've talked about is "Shadows" -- see https://www.youtube.com/watch?v=SJH9iFOji_A https://www.youtube.com/watch?v=SJH9iFOji_A In the interview I saw, they don't talk about how they actually do it, but they've talked about the ways they could do it, or have done it in the past, but don't anymore -- and why. Good luck finding that interview. I found it extremely interesting, but can't dig it up at the moment.
