Getting started with a cocos2d v2.0 image warp app / ccgrid / ccactiongrid
===

I have to make an app that takes an image of a face, allows the user to indicate the location of main features like eyes and mouth and then warp the image to give a particular expression (smile / frown).

My thinking is that I could use a few component ccgrids for the mouth / eyes separately and then combine these to make a live ccgrid to be applied with a ccactiongrid.

First of all is this a sensible way to approach this?

Secondly, I can't find any examples of how to work with ccgrid objects or ccactiongrids. Are there any examples out there that I'm missing or could someone give me a crash course?

Thanks,

Martin
