It is the artist Marc Quinn's most ambitious project to date. And that's saying something.
Because this is a man who came to prominence after filling a cast of his head with ten pints of his own blood.
Now, he's aiming to repeat the trick - this time in collaboration with refugees.
The aim is to raise awareness - and cash - to support their plight.
"Our Blood" mixes the blood of thousands of people - half of them refugees.
Fatima Manji has been to meet him at his studio.
