Your2face is another creation of iPaguri.com (the guys from CalcPaper). This time they created a little application that let’s you make ‘chimeric faces’.
What are chimeric faces?
A chimeric face is created by dividing an image of a face vertically through the midline. Then, the two left-left (LL-composites) and two right-right (RR-composites) hemifaces are combined to make composite faces with only LeftLeft or RightRight hemifaces. You really get funny pics this way.

This version looks very professional and i guess this might make it to the Apple Appstore.
