You do discover some crazy things when awake in the middle of the night in a slightly feverish, headachey state of mind.
I discovered a site which allows you to morph photos of faces, including pre-uploaded celebrity visages. It's great fun! Seeing as my idol is Audrey Hepburn and I personally believe her to be the archetype of beauty, I mixed her face with those who are considered most beautiful at the moment, and particularly those who I believe share some similarities in facial structure. It's amazing what you notice about facial structure when you look properly. Can you study this in college, I wonder?
Here are the results:

(Pay attention to the Calista Flockhart one - the nose doesn't change!! Check out the second link below that one - Kevin Aucoin made her up to look like Audrey Hepburn and her facial structure is really incredibly similar even if the resemblence does not strike you at first - although there is something slightly grotesque about the picture that I can't put my finger on.)
