Frances Wadsworth-Jones' jewelry design show ("Heaven Sent") at the Museum of London runs until April, with centerpiece brooches that resemble bird droppings. Why, she was asked, would a woman want to wear jewelry suggesting a pigeon soiled her lapel? "The stain is very intimate," said the artist. It's "something that you wouldn't want, and you're turning it into something beautiful." Wadsworth-Jones' pieces have sold for as much as $4,000.
