Does Maynard James Keenan (front man of "A Perfect Circle") have a tattoo of the bands logo on his chest?

I have searched and searched and can not find a picture or proof that it is a tattoo. You can clearly see it on his chest in the band's video "3 libras". I've heard that it's actually not a tattoo, but metal pieces bent and somehow placed into his chest. I've also never heard of that type of body art before. I would love to know what it really is.
