Damien Hirst's retrospective is now at the Tate Modern in Britain, and the Guardian has some interesting features on aspects of his work. The butterflies have always been one of my favorite of Hirst's "media," if that term applies.
He discusses making the platinum and diamond skull here.
I am weary of Hirst. Doesn't it seem like the art world sort of forces us to acknowledge and discuss his work? If there is enough money involved, you can't tune it out. Sort of like Mitt Romney.
