Artist Jason Salavon is doing strange things.

Take this, for example—every Playboy centerfold from 1960 to 1999, grouped by decade and digitally averaged into one composite photo for each decade.

We can clearly see that the models have become whiter, blonder, and skinnier. And the background has blued. Click through for closer views of each image.

The entire surface area of the artist’s body is printed to scale in this photograph. It consists of over 13,000 half-inch squares of skin and hair rearranged vertically by luminosity from dark to light. The resulting self-portrait is reconfigured so as to reveal the most intimate physical detail while obliterating individual identity.

The result looks like this:

But you have to see the detail to get the full effect.

There are more, like the 76 Blowjobs, or The Grand Unification Theory (one frame per second from Star Wars, arranged by luminosity).
