In the spirit of statistically optimal music, I give you Average Porn.
The photographs in this suite are the result of mean averaging every Playboy centerfold foldout for the four decades beginning Jan. 1960 through Dec. 1999. This tracks, en masse, the evolution of this form of portraiture.
The change in hair color is the most strikingly obvious detail. I want to say it looks like they're getting skinnier too but I don't know if I'm reading that into the images based on my expectations or if that effect is really visible. It seems like the poses must not vary much. I've actually only seen like 2 actual playboy centerfolds so I don't have a lot of experience with the source images here.
Oh and completely unrelated, here are those VERY WRONG G. I. Joe remixes that I have mentioned to some people here and there.
