Spencer Tunick got twice as many people turning out for his latest mass nudity photograph in Sydney, Australia, according to BBC News:

More than 5,000 men and women shed their clothing – people of all ages, shapes and sizes, who were undeterred by the chilly pre-dawn weather on this, the first morning of the southern autumn.

Tunick, famed for his snapshots of mass nudity in public spaces, had been commissioned by the organisers of Sydney Gay and Lesbian Mardi Gras, which took place over the weekend.

The naked models included a pregnant woman, who went straight to hospital afterwards to give birth, and a television weatherman whose viewers got to see considerably more than his usual Monday morning forecast.
