Many years ago British artist Marc Quinn started an art project where he created cast self-portraits using his own frozen blood. On one hand, it's incredibly creepy and unsettling. But on the other, how many artists' can turn to their creations during a medical emergency?
Starting as far back as 1991, Marc has been creating these self-portraits every five years or so, with each one requiring about four and a half liters of blood extracted over a five-month period. And while it might sound like a macabre medium to work with, as we've pointed out in the past, crafting in blood is far cheaper than making a copy of your masterpiece with an inkjet printer.
