I don't have a clue.
I ran accross this yesterday and I can't fathom it. The site features a female doll photographed in various situations as if she were a model. There's lots of photos, but I only looked at a few of them. (I couldn't stand the idea of a piece of plastic having more of a life than I do.) The photos don't seem to be sexual in any blatant way; this isn't some violent, disturbing tableau like the work of Surrealist artist Hans Bellmer, but something about this stuff is vaguely unsettling. Maybe if I could read the Japanese text I'd find it all perfectly logical and innocuous. Maybe. [Link via 104 Random Altavista Pictures.]
