That's artist Marc Quinn polishing his latest creation: a golden statue of Kate Moss, who he called a "modern day Aphrodite," in a particularly limber pose.
It is the largest gold statue made by man since ancient Egyptian times, weighing 50kg, around the same as its subject.
Artist Marc Quinn, whose previous works include the sculpture of a pregnant woman with no arms or legs on the fourth plinth in Trafalgar Square, said Siren cost £1.5m to make, £1m of which was for the gold.
What does Kate Moss think about all of this?
"For Kate, she thinks it lifts her into a mythical level," he said. "I think she very much loved it because she understands the difference between her image and her self.
"The sculpture is really about whether we make images or they make us. It's about trying to live up to impossible dreams and immortality."
