Morphing?

I recently was at Circus Circus in Las Vegas and they had a photo vending machine/booth where two people took turns having their picture taken and the machine would morph the faces together and show how their child would look. It was pretty cool. Is there a Photoshop filter/plugin that could do this? Or does anyone know how to do it? (Even if it is annother program) Thanks!

This is the place where you should post your sigs and small graphic things you have created...
