Help, need a morphing program? 10 points?

I am doing a personal age progression (0-23 yrs) and want to realistically morph all 23 pictures, I know fantamorph is really good, I need a program that pin points certain features of the face to make it look more natural. I have a MAC OS X 10.4 and need a program suitable for a 10.4 MAC. But I need it free, whether that be a trial or the real software. Just as long as I have a few hours to make a 23 pic morph. I tried Morpheus, I downloaded it and it told me to pay, then I get a code in a email... otherwise, I can morph only 2 pics and the multiple pic feature is not possible for free. So........ any ideas???? 10 points best answer.
