"Apple Motion" to create demon face warp effect?

I have a project where the well-known "demon face warp" effect would be ideal. I understand that it's quite doable with After Effects. But since I don't own After Effects, I thought I might see how to do it with Apple Motion.

My footage is from a Sony EX-1. It's footage of a blonde actress in the woods. I'd like to demonize her pretty face.

(I have FCP 6 and Motion 3.)

Do any of you know of a good tutorial on this subject? Or can any of you suggest how I best expore using Apple Motion for this on my own?

thanks,
