This weeks WP7 AOTW is Face Swap by Microsoft Research.

This app, to put it simply, swaps two people’s faces. There is no practical purpose to this app as it is just to waste time. To use this app, you simply select a photo in your photo albums and the app automatically finds the faces in the image. You then proceed to select which faces to swap and the app does all the rest. You can then proceed to laugh at the results.

Simples.
