Vincent Castiglia is a highly unconventional artist and tattooist. Whereas most people normally paint with oils or acrylics, Castiglia prefers to use human blood when he is not tattooing. That's right, straight from the vein, blood. While some people may find this pretty creepy, we find it pretty damn cool, and apparently so does comedian Margaret Cho. According to TMZ, Cho found it cool enough to commission a sanguine portrait of her very own, and even supplied her own blood for the project. After six months with Castiglia drawing blood, both with a needle and on a canvas, the commission is finally finished and ready for the public to see!
