Warp just a subset of a plot

Hello, I'm trying to warp and move around aspects of a plot. I'm using Doug's George body figure. http://blogs.mathworks.com/images/steve/37/maketform_tformfwd_01.png http://blogs.mathworks.com/images/steve/37/george.mat

And I'm trying to find a way to, say, just bend it's head to the side, or say stretch it's sides so it looks like it has arms.

I image that i could some how tessellate the points and use this to some how pull everything, but I really don't know where to start.

any help would be greatly appreciated.

More specifically, goal is to be able to pick a point on this body outline, move it to some other location, and have the neighboring points move with it in a smooth way.

now, this doesn't need to be that pretty, just wanna make it do "basic" warps, like nod and stuff. doesn't need to be very clean.

thanks!

i'll definitely look at that right now. I'll close this question a little later when I think i have a handle on the problem (so that I don't start spreading my question around if I run into issues).

thank you, big fan of your posts!
