I "stumbled" across thishttp://xupacabras.weblog.com.pt/arquivo/fotos_de_c orposnudes_photos/
It's a few years old but it was a blog filled with lots of interesting artistic nudes.
It's too bad the images are so small. I think they're small so that we wouldn't bother manipulating them, but regardless I found several of the images quite inspirational.
Lots of the images even have woman grabbing themselves.
