"The Ghost" is an escape from the SideMount position that the guys over at 10th Planet Rochester have put a video together for.
Chris Herzog, the head instructor over there, does a great job of breaking this technique down in the video above. This is a really slick escape that will take you from a bottom inferior position to a top dominant one. Imagine that, not only are you escaping but you are going to the top position almost as if you just did a sweep.
Definately like this one and the principle can be used in a variety of positions.
