Ragu Spaghettisauce

It has been done many times already (I first heard about it in some psych class years ago in college), where you combine many photos of people and then the composite outcome is considered "above average" - so movie stars and the like tend to have faces that are just "extremely average" and we see that as attractive.
(and I think I recall that "supermodels" in terms of runway and the exotic look, are actually freakishly different, as opposed to aggressively average - but for success in the lowest common denominator magazine cover and movie world, the average look is best)

Shows close-ups of celebrities, and they are all pretty close in setup, so it would be interesting to merge/morph/average all of those together and see what you get (I would imagine Iggy Pop's facial hair, Marilyn Manson's face paint, and Tom Hank's refusual to look directly into the camera would throw off the results, as would the small sample size)
