Is This What Some People Consider Pornographic?

The above image is the cover art for the forthcoming Metallica album, Death Magnetic. Some are suggesting that the image features a subliminal, pornographic allusion to a certain female body part. I don't suggest that, and frankly, if you are, you have the dirty mind. I see the grave and casket as representing "death" (obviously) and for the "magnetic" part, it is the dirt moving away from the casket. It's like magnetic particles being pulled away by a larger magnetic (or something like that). I don't know about any larger meaning, but I don't see anything sexual about it. Save the deep thinking for analysis of the album's content (i.e. the music).
